Where does the "right hand rule" of magnetism come from?

This is just a simple teaching video, which I made because NOBODY seems to understand basic physics in 4-D xyzt!
Abstract equations as taught in the schools are just "chicken scratching" as Einstein said.
Without understanding basic concepts, those abstract equations mean nothing.
James Clerk Maxwell would have liked this video, but I am not sure how it will go down with the modern "chicken scratchers" LOL?
Best wishes to all, Red Collie
