5. Answer the following questions. How does an electric bell work?
Answers
The electromagnet is powered and generates a magnetic field that attracts the iron strip towards it. The striker strikes the gong (bell). When the striking arm strikes the gong, the contact is broken and current stops flowing through the circuit. This causes the electromagnet to lose its magnetic field.
Answer:
An electric bell has Electromagnet in it. It is made up of two rods of cast iron. The iron rods have a coil wrapped around them. A metallic strip is used and is kept parallel to the coils. This trip has a Hammer connected to it at one end. The other part of the strip is connected with the circuit. A gong is placed in such a position that it can be hit by a hammer. When electric current is passed through the circuit the cast iron rod becomes charged with electromagnetic energy and attracts the metallic strip. as a result, the metallic hammer hits the ground the circuit breaks when the metallic through peaceful towards Electromagnet and gets disconnected from the point .since there is no magnetism left an Electromagnet the spring pulls back the metallic stripped this cycle is repeated again and again in the electric bell which produces a ringing sound .that is why it is called as making brake circuit.
