Solution
The correct option is D All the above.
- An electric bell works on the principle of electromagnetism.
- Magnetic induction is the process in which a magnetic substance becomes a magnet when it is kept near a magnet without there being physical contact between them.
- An attractive property is a property of a magnet where a magnet attracts substances like iron, cobalt, nickel, etc when brought near it.
- The electric bell consists of the electromagnet.
- When the electric bell circuit switched on current flows through the electromagnet which creates a magnetic field that attracts the iron armature and this armature produces the ringing sound.
Hence, An electric bell works on the principle of magnetic induction, an attractive property of magnets, electromagnetism.
Therefore, the correct option is option D.
