When an electric bell is operated, a current pass through an electro-magnet intermittently. The plunger moves back and forth due to intermittent magnetic operation. The moving plunger or lever connected to it hits a metallic body intermittently to ring the bell. The movement of plunger itself cuts off and cuts in the electric circuit intermittently.

Which jobs use electromagnets?
Probably the most important use is in the electric generator. They are used in metal detectors, and speakers. In generators they are used to generate a constant charge. In metal detectors they are used as a sensor; where the field is changed by metals in the ground. And in speakers they are used in a to and fro motion on a diaphragm to make sound.
The discovery of electromagnets led to the invention of electric motors.?
Yes it did
