A common real-world use of a solenoid is in automobile starter systems. In this application, the solenoid acts as an electromechanical switch that engages the starter motor when the ignition key is turned.
When the driver turns the key, an electrical current flows to the solenoid, creating a magnetic field that pulls a plunger, effectively closing the circuit and allowing battery power to flow to the starter motor. This action enables the motor to crank the engine, allowing the vehicle to start. Once the key is released, the current to the solenoid is cut off, and the plunger returns to its original position, disconnecting the starter motor.
This use of solenoids is essential for starting internal combustion engines in many vehicles.
