Demo of making electricity with coil, crank, and Stirling engine

I did this talk early on in the pandemic as part of a kid's event for the Pacific Science Center in Seattle. I hook up my oscilloscope to a coil of wires and show that you can move electrons around with a magnet.

great demo. EE hers. Note not really “pushing electrons around”. Common mistake. Waving that magnet induces an electric *field* which the electrons enable, and the field registers on the scope.
