Why magnetic monopoles do not exist

There’s a lot of articles about magnetic monopoles. See this for example: the hunt for magnetism’s elementary particle begins. It dates from 2016, and it’s by Avaneesh Pandey. He says this: “magnets, for reasons we still do not understand, seem to exist only in the form of dipoles - ones with a north and a south end. Break a bar of magnet into two, and you still do not get a magnetic monopole. Instead, you now have two smaller magnets, each with its north and south…

How a magnet works

There's a rather interesting Discover magazine article called Three Words That Could Overthrow Physics: “What Is Magnetism?”. It was written by Bruno Maddox in 2008. The subtitle is "The standard model still doesn't describe magnets' spooky action at a distance". Maddox was on holiday reading Electronics for Dummies when he realised that he didn't how a magnet works. He said this: "I set out on what I assumed would be a minutes-long odyssey to understand the phenomenon. Seventy-one days later, I am here with astonishing findings.…

The screw nature of electromagnetism

If you’ve ever read Maxwell’s On Physical Lines of Force, you may have noticed this: “a motion of translation along an axis cannot produce a rotation about that axis unless it meets with some special mechanism, like that of a screw”. Maxwell was referring to what I can only describe as the screw nature of electromagnetism. If you have a pump-action screwdriver you’ll appreciate that linear force is converted into rotational force. That’s like an electric motor: current flows through the wire, and the motor turns.…
