Re: falling magnet demo

I tried a classic demonstration of dropping a magnet through a copper
tube at the same time as dropping an unmagnetized bar. They both

I think this demo is normally done with neodymium supermagnets. The
magnet should be a stubby rod in shape, with only a small clearance around
the tube, a "slip-fit" in other words.
