We just learned about the Electromagnet.
Another part of the electric motor is the Air Gap.
We learned that the rotor is the part that spins around in the middle, and the stator is the part that is wrapped around it.
The very small space between the rotor and the stator is the air gap.
The smaller the air gap, the better the electric motor will work, but it also needs to be enough space that the rotor won't hit the stator as it is spinning around.
