What is a permanent magnet?
Dec 27, 2018

That is a good question because it is always assumed that a permanent magnet is due to the way in which electrons move around the nucleus, because you need a movement of charge to produce a magnetic field. the trouble with our thinking on permanent magnets is that a movement of charge requires energy from some source, which clearly is not obviously available.

But the obvious is not always obvious. Science often makes assumptions which are based on obvious truths, which later down the track turn out to be incorrect. So let me suggest a hypothesis: Every atom and all its constituent parts move or vibrate continuously, and some universal forces or fields keep all atoms and their parts in motion, including the movement of charge to make a permanent magnet.
