How does a solenoid cause your doorbell to ring?

A solenoid in a doorbell system consists of a coil of wire and a movable metal core (plunger). When you press the doorbell button, an electrical current flows through the coil, creating a magnetic field that pulls the plunger inward. This movement strikes a bell or chime, producing the ringing sound. Once the button is released, the current stops, and the plunger returns to its original position.
