For teachers Computer hardware and electronics, middle school through introductory college courses

A classroom demo motor you can actually get your hands into. Slide the magnets, dial the voltage, rewind the coil, slow time down to watch the commutator flip the current, then spin it by hand and light a bulb.

In class: A working motor to take apart: slide the magnets, change the voltage, rewind the coil, and use it as a generator.

Students need no account and nothing to install, so it works on Chromebooks and as a sub plan.
