The electron doesn’t have an electric field, it has an electromagnetic field. If you’re a positron and I set you down near a motionless electron, you will move linearly towards it, and it will move linearly towards you. So you might think the electron has a radial electric field, which results in a linear electric force. But it doesn’t. That linear force is there because the electron has an *electromagnetic* field, and so do you.

*Linear and rotational force*

Moreover the interaction between these fields doesn’t just result in linear force. If you’re a positron and I throw you past that motionless electron, the force between you and the electron is no longer just linear. There’s a rotational magnetic force too. So you might think the electron now has a magnetic field, which results in rotational magnetic force. But it doesn’t. That rotational force is there because the electron has an *electromagnetic* field, and so do you.

*You do not create a magnetic field by moving a charged particle*

The crucial point to note is that I didn’t create a magnetic field for that electron by moving *you*. I don’t create a magnetic field by moving a charged particle. Because that charged particle always had an electromagnetic field, because it’s a “spinor”. And because it takes at least *two* such particles to exert linear and rotational force on each other. An electron is not surrounded by a field of force, or two fields of force. Nor is a positron. Because linear and rotational force is the product of at least *two* electromagnetic fields interacting. It takes two to tango in the positronium dance of death:

Field and force are not the same thing. Force is there when two or more electromagnetic fields are interacting, be it the linear electric force or the rotational magnetic force, or both. When we contrive our charged particles such that the rotational forces cancel, we only see the linear forces, and we talk of an electric field. When we contrive our charged particles such that the linear forces cancel, we only see the rotational forces, and we talk of a magnetic field.

*Electric charge is a misnomer*

But there are no charged particles where the force is only linear, and there are no charged particles where the force is only rotational. So there are no particles which only have an electric charge, and there are no particles which only have a magnetic charge. The particles feel both the linear electric force and the rotational magnetic force. So electric charge is a misnomer. The electron has an electromagnetic field, so it has an electromagnetic charge too.

*Electric and magnetic fields exist*

That’s not to say there’s no such thing as an electric field or a magnetic field. The region near a thundercloud is not the same as the region near a magnet. An electric field is a place in space where the rotational forces on charged particles cancel, and we only see the linear forces. See the Wikipedia Coulomb’s law article: *“an electric field is a vector field that associates to each point in space the Coulomb force experienced by a test charge”*** .** We draw electric field lines between the plates of a capacitor to mark out this linear force. But the force depends on the charged particles involved. An electron will move along the field lines one way, whilst the positron will move the other. Meanwhile a magnetic field is a place in space where the linear forces on charged particles cancel, and we only see the rotational forces. See the Wikipedia magnetic field article: a magnetic field

*“*

*exerts a force on other nearby moving charges and magnetic dipoles. At any given point, it has a direction and a magnitude (or strength), so it is represented by a vector field”.*We draw magnetic field lines between the poles of a magnet to mark out this rotational force. But again the force depends on the charged particles involved. An electron will move around the field lines one way, whilst the positron will move the other.

*A field is a state of space*

These particles move the way that they do because they are what they are, and because space is what it is. In his 1929 history of field theory Einstein described a field as a state of space. The state of space where the electric field is, is not the same as the state of space where the magnetic field is. They are different, but no so different, just as the positron is not so different to the electron. Because like the Wikipedia electromagnetic radiation says: *“the curl operator on one side of these equations results in first-order spatial derivatives of the wave solution, while the time-derivative on the other side of the equations, which gives the other field, is first order in time”*. And like Minkowski said, *“**the division of the field into electric and magnetic forces is a relative one with respect to the time-axis assumed”. *As to what the state of space is for electromagnetic fields, there’s a clue in something else Minkowski said.

*Space is twisted, space is twisting *

Minkowski referred to one field only, and we didn’t create the electron and positron in gamma-gamma pair production using an electric wave and a magnetic wave. We used electromagnetic waves. The electric aspect of each electromagnetic wave is the spatial derivative of electromagnetic four-potential. The magnetic aspect of each wave is the time derivative of electromagnetic four-potential. It’s like the canoe analogy where the electric field E is denoted by the slope of your canoe, and the magnetic field B is denoted by the rate of change of slope. They are two sides of the same coin, they cannot be separated. This is why Minkowski also said “*the two forces considered together can most vividly be described by a certain analogy to the force-screw in mechanics”. *When you turn a screw, rotational force is converted into linear force because the screw has a twist. When you work a pump-handled screwdriver, linear force is converted into rotational force because the shaft has a twist. The electron and the positron move like they do because *space* has a twist. Because the electromagnetic field shares some similarities with the gravitomagnetic field. As you might expect if you know that Oliver Heaviside developed gravitomagnetism as an analogy of electromagnetism. See the NASA GPB article by Tony Phillips where you can read that *space is twisted. *Also see the beautiful gravity probe B video by Bob Kahn and James Overduin, animated by Lee Kolb and Greg Trent with music by Ray Lynch:

I think it’s best to think of the electromagnetic field as a place where space is twisted in a 3D chiral fashion. Then when you think of electrons and positrons it’s easy to visualize that they move the way they do because each is a dynamical spinor in frame-dragged space. Each is a spin ½ standing-wave “twist” field with its secret Poynting vector going around and around. Each is situated in the twist field of the other. Each is like a vortex, but they have the opposite chirality, and counter-rotating vortices attract. When the source of this twisted space is moving relative to you, it’s like space is twisting and turning. It’s like being in a “turn” field. Hence the screw nature of electromagnetism is all about twist and turn, and so is charge. Because when you throw one vortex past the other they swirl around each other as they attract. The linear and rotational forces they feel are local to them, because of what they are and the space that they’re in. Not because of some magical mysterious action-at-a-distance force. Not because they’re throwing photons back and forth. The only photons you’re going to see are when the electron and the positron annihilate. Then there’s no charge any more. Because charge is not fundamental.

*Charge is not fundamental*

If you look around on the internet you’ll see plenty of articles saying charge is fundamental. It isn’t. *Energy* is fundamental. Energy is the one thing you can neither create nor destroy. You can create charge, and you can destroy it, in gamma-gamma pair production and annihilation. And when you’ve created your charged particles you can diffract them, because of the wave nature of matter. You started with photons, with waves that propagate linearly at c. You ended with electrons and positrons, with waves that *don’t* propagate linearly at c. Instead the electron has its spin, and so does the positron. Like Feynman said, there’s angular momentum in the field. And like the Einstein-de Haas effect says, that angular momentum is of the same nature as the angular momentum of rotating bodies. So something is going around and around. What could it be? Cheese? Magic? Probability? I don’t think so. It think it’s obvious what’s going around and around: light. Or an electromagnetic wave if you wish. Or a pulse of potential if you prefer. Or wavefunction if you will. Only it isn’t so obvious that it’s a wave. Because when the wavelength is just right and it goes around and around just so in a spin ½ twisted fashion, the field variation doesn’t look like a field variation any more. That’s because at all locations around the closed path there’s a superposition of two field variations that add to the same field value. So it looks like a phase-invariant standing field. Hence in atomic orbitals electrons exist as standing waves. Hence outside of atomic orbitals, electrons *still* exist as standing waves. That’s all that’s there. There is no billiard-ball at the heart of the storm, and there is no point particle at the heart of the electron. Because the electron’s field is what it is. Because charge is what we call it when a chiral electromagnetic wave goes round and round just so, such that it doesn’t look like a wave any more. Instead it looks like a standing field. *Standing wave, standing field.* But that isn’t quite enough, because it doesn’t tell you why the wave goes around and around. To know that, you have to know that charge is *shiny*.

*Charge is shiny*

There’s a nice little reader-friendly article on charge by Bill Beaty. He’s an electrical engineer at the University of Washington in Seattle. He says this: “*Metals look metallic because they contain a ‘fluid’ composed of movable electrons. This electrical ‘fluid’ is an excellent reflector of light waves, and it causes the surfaces of metals to act like mirrors. It’s these same electrons which flow during an electric current’. *You find other articles saying much the same thing. Google on electron metal shiny and take your pick. For example see the partial lesson about the electron sea model by Amy Meyers. She says it explains many of the physical properties of metals, and metals reflect light because of the free electrons. The thing is this: when you look at a shiny metal, what you’re seeing is this electron sea. It’s important not to overthink this, and instead think about what you’re seeing: electrons. And these electrons, these charged particles, are shiny. So when you read Bill Beaty saying “*The ‘silvery’ stuff of a metal is the charge” *it shouldn’t come as a surprise. However what might is that you’ve seen something similar on a sunny day. We call it a highway mirage. Light is distorted because the path isn’t straight. The result is *shiny*. The path isn’t straight after pair production either. Instead the path is curved. Light shines and charge is shiny for the same reason: because light consists of electromagnetic waves propagating through space. It’s important not to overthink that too.

*Space waves*

When an ocean wave propagates through the sea, the sea waves. When a seismic wave propagates through the ground, the ground waves. And when an electromagnetic wave propagates through space, *space waves*. There *are* no waves where something doesn’t wave. And where that something is waving, it is curved. So something else passing through that something will follow a curved path. If that something else is light, its path will curve. When light moves through space where light is, light curves. Then when light moves through itself just right, its path can curve into a closed path. Not because of some magical force. But because like Percy Hammond said: *“the field describes the curvature that characterizes the electromagnetic interaction”. *And because like Maxwell said, *“light consists of transverse undulations”.* Maxwell was talking about displacement current. It does what it says on the can. It displaces things. Things like waves in space. Waves in space displace waves in space. Waves interact. Light interacts with light. Not just with matter. If light didn’t interact with light, there wouldn’t *be* any matter.

*Light is curved space*

Light is a wave in space, so light is curved space. The degree of curvature varies with the wavelength. When you play a guitar the amplitude of your pluck is always the same, but the curvature of the string is greater when the note is higher. A photon is something similar, with Planck’s constant h corresponding to your pluck. Then when you play a very high note, when the wavelength is 2π times the amplitude, a wave of spatial distortion can interact with a similar wave and curve such that it ends up moving through itself. Then its path keeps on curving, and light ends up doing what a hedgehog does: it curls up into a ball.

*Charge is all-round spatial curvature*

That’s when we call it charge. An electromagnetic wave consists of a positive field variation followed by a negative field variation. Field is the derivative of potential, so you can draw a sine wave to represent the electromagnetic wave, then you can draw the potential as a sinusoidal hump. The hump is highest in the centre where the sine wave goes from positive to negative. The electromagnetic field there is zero, but the potential is at a maximum:

When you twist it round and wrap it up in a spin ½ configuration, it’s like making a Möbius strip. The positive field variation is rotated into negative field variation, then two negative field variations combine to create an all-round negative standing field. Alternatively when you twist it round the other way the negative field variation is rotated into a positive field variation, then two positive field variations combine to create an all-round positive standing field. The two alternatives have the opposite chirality:

You now have a spinor of sorts. However space is not a flat strip. Instead the electron is spherically symmetric, and so is the positron. To visualize this you have to inflate the strip into a ring torus, then a horn torus, then a spindle-sphere torus. The result isn’t a spinning ball of charge. It’s a bispinning wave of light, with a spherical centre like the eye of the storm. Only it’s a standing wave too, so you can’t see that it’s spinning:

Now you have an all-round spatial curvature. The strong curvature regime isn’t where a black hole is, it’s where the centre of an electron is. This curvature diminishes with distance from the centre because the electron’s field is what it is. It’s a charged particle, with a charge of 1.60217662 × 10^{-19} Coulombs. That’s “unit” charge, and it’s unit charge for a very good reason.

*Unit charge*

An electron is a charged particle, an all-round standing wave where an all-round spatial curvature makes a 511keV photon go round and round. This charged particle has unit charge, and it has it for a reason. To understand this reason, you need to do is draw an all-round circle.* *

Imagine what would happen if I performed a Compton scatter on this thing. The frequency of the incident photon is reduced. It’s as if I peeled a slice off that photon and slapped it onto the electron. This electron has a Compton frequency because it is in essence a 511keV photon. It’s in a spin ½ configuration, but you can diffract it, so it’s still a photon at heart. When you combine two photons into one you increase the frequency. So we have increased the frequency of our electron, and increased its energy. And because the degree of curvature is related to frequency, we have increased the curvature. Imagine you had to increasing the curvature of a circular piece of wire. It’s very difficult to compress the wire all round into a smaller circle. But it’s very easy to increase the curvature if the wire has two free ends. You could increase the curvature like this:

Now it’s more than a circle. There’s more than 360° of curvature. Now we have *more* than unit charge. But remember the electron is a dynamical spinor, so draw another circle on the end of the first. Then another and another. Now what you see, is that if the circle is more than a circle, if the curvature is more than 360°, if we have more than unit charge, the electron *moves:*

Throw a photon at an electron and the electron is still a standing wave, but it isn’t standing still any more. You might be, but when you chase it and catch it up and measure the charge, what you measure is unit charge. Because in your frame, the electron path is circular again.

*What charge is*

An electromagnetic wave is a wave in space, a place where space waves, and so a place where space is curved. Like William Kingdon Clifford said in his space theory of matter, *nothing else takes place*. Gamma-gamma pair production is merely what we call it when two such waves each displaces the path of the other into itself, whereupon each wave displaces its own path into a closed chiral path. Then each sinusoidal field variation is configured as an all-round standing field, and we apply the label *charge*. So a charged particle like the electron is a spindle-sphere electromagnetic wave in a standing-wave spin ½ spinor configuration, and charge is a place in space with an all-round spatial curvature that goes full circle. This curvature reduces with distance akin to frame-dragging, and since there are no circles of more than 360°, we have unit charge. We talk of positive charge and negative charge, but the positron is a place where space is curved just as much as the electron, just as your left-over-right shoelace is curved just as much as your right-over-left. There is no negative curvature, there are no sources and sinks, there are no magnetic monopoles, there are no virtual particles popping in and out of existence, spontaneously, like worms from mud. Light interacts with light, there are no point particles, spin is real. The electron field is just a trivial-knot disposition of the photon field, messenger particles are more fundamental than the field they’re supposed to mediate, and charge is topological. All in all there are some issues looming for particle physics. Particularly when you realise that we’ve never ever seen a particle with color charge. All the more so when you appreciate that all charged particles have *mass*.
