I'm not a scientist, man, I can't name all this shit off the top of my head. It's not electromagnetic on its own but it does develop an electromagnetic field when placed into a magnetic field that is moving around it.

You know those flashlights you charge by shaking them? Same principle. You've got a magnet inside of a copper coil, when the magnet moves inside the coil the copper (a metal which is not usually magnetic) becomes electrified, which charges the battery.

Aluminum does the same thing. I think that does count as electromagnetism but I'm not 100% sure of the technicalities since, as noted; not a scientist. Just a smartass.
