I have to say, though, I am less than convinced. Say I create a new permanent magnet. How do other magnets know about it? In other words how does this “field” propagate? As it carries information it must surely propagate at the speed of light – but how? Is it a property of space-time itself?
How does the electromagnetic force get turned into kinetic energy? Do all the electrons inside a magnet ‘rush’ to one end of the magnet – if so why don’t we see an imbalance of charge (or maybe we do – after all magnets can be used to generate current).
Fear these questions may lead some of you to doubt I have any sort of physics qualification at all – but I do not recall being taught any of this, at ‘O’ level, ‘A’ level or as an undergraduate.
