What does a car solenoid do?

Answer

Solenoid is the general term for a coil of wire used as an electromagnet .In a car ignition system, the starter solenoid acts as a transmitter, bringing metal contacts into position to close a circuit. The starter solenoid receives a small electric current when the car's ignition is activated. The magnetic field of the solenoid pulls on the contacts, completing the circuit between the car's battery and the starter motor.

A car solenoid refers to a part of an automobile starting system. It receives a large electric current from the car battery and another small electric current from the ignition switch. Solenoids can be built into a starter itself depending on the brand of a vehicle.
