Explanation:

They can be used to slow the flow of electricity in a circuit, making them an example of an inductor, or an impedance device. Cars also have a type of solenoid that is really just a motor that happens to work using a coil of wire. The job of the solenoid is to turn electrical energy into movement.

Answer 2
