When the switch of an electric bell is pushed

1. Flow of the current stops through the electromagnet in the bell
2. Current starts to flow through the electromagnet
3. voltage decreases in the current flowing through the electromagnet
4. None of the above

Correct answer: Current starts to flow through the electromagnet

Solution

An electric bell works only when the circuit is closed. Pressing the switch completes the circuit, so current begins to flow through the electromagnet and it becomes magnetized.
