Make thin copper wire. (Or other metal should work. Anything you can work into a thin wire. Copper is one of the easiest to make thin wire from, but gold would also work well if you can afford it.)

Coat the wire in a thin layer of wax.

Coil the wire.

Spin a lodestone rapidly inside the coil.

Electricity will then come from the ends of the wires.

Come on, people. Stop reveling in your ignorance and go learn something.
