Description
There are a number of science museum exhibits which require many tens of amperes of electric current in a thick cable to generate strong magnetism. One example is a raft of compasses with a 200-amp cable running through the center of the raft. Or, three 100-amp cables with three-phase AC powering them, where the resulting field rotates and can spin a conductive object by induction. Rather than trying to build a 2-volt, 200 ampere supply, there is an easier way.
