How can I get an AC current going through it?
Hook it up to an AC voltage source?
My teacher said that there was a way to make a commutator with aluminum wrapped around a stick and cut on one side. How would that work?
It would allow you to apply current for only half a turn.
The principle is the same as:
... only, there, the insulation has been filed off half the circumference of the wire.
