Well, now its 10/99, and several people HAVE yelled at me, but it still
didn't get me up off of my butt.
VISIBLE SUPERCONDUCTOR PLATE
The 'visual electricity' device lets us see the motion of the charges
inside of a wire. This might be helpful for visualizing how circuits
work, but what about conductors which are not one-dimensional? For
example, what does the current in a piece of copper sheet look like when
the terminals of a battery are touched against it? Or, when a supermagnet
rolls down an aluminum plate, and electromagnetic braking slows the
motion, what does the current in the plate look like? Or, when a magnet
hovers above a superconductor plate, what is the motion of the charges in
the plate?
