Explain the structure, construction and working of an electric bell
Answers
The construction of an electric bell:
The construction of an electric bell consists of a gong, an electromagnet, a soft iron rod and a contact screw.
The working of an electric bell:
When the current passes through the electromagnet, it becomes magnetized which helps to attract the armature and after this the hammer raids and attract the armeture. At that time, electromagnet didn’t behave as a magnet because of the breaking contact with the screw. So, again armeture comes down to make the contact with the screw. This cycle keeps on repeating.
Answer:
Structure - The Electric bell consist of -
1. Gong 2. electromagnet 3. hammer 4. soft iron armature
Working - when we press switch the electric current starts flowing in the circuit. The electromagnet starts producing the magnetic field which attracts the iron strip towards it as a result the hammer strikes the gong and sound is produced . now as we release the switch , the electric current supply stops as a result the iron strip come back to its initial position and bell stops ringing .
