What Does a Car Solenoid Do?


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.
