Question

In the case of an electric bell, the armature is fixed in such a way that it opposes the poles of a magnet.

• A. True
• B. False

Answer 1

The correct option is B False

1. In the case of an electric bell, the electromagnet is connected to a metal strip called “armature”.
2. The armature is fixed in such a way that it faces the poles of the magnet.
3. The armature has to face the poles of the electromagnet and also get attracted by the poles of the electromagnet so that the electric bell works properly.
4. When the switch of the bell is “on”, the electric current flows through the coil of the electromagnet of the electric bell, and the electromagnet starts behaving like a magnet.
5. The electromagnet due to its attractive property starts attracting the armature.
6. When the armature moves towards the electromagnet, the hammer connected to it hits the gong, and sound is produced.
7. Below is the diagram showing the armature and other components of an electric bell.

Hence, the given statement is false.
