Electric Motor

We just learned about the Bearing.

One type of motor used for a lot of things is an Elecric Motor.

This motor usually has some electric coils wrapped around a metal pole, spinning around inside a tube.

Some electric motors use the tube to force the pole to spin, and others take the energy from the spinning pole and use it to charge up electricity from the tube around it.
