Why is the core of the coil used in the circuit of an electric bell made of iron? (choose the most appropriate answer)
Why is soft iron used as the core of the elctromagnet in an electric bell ?
Why is soft iron used as the core of the electromagnet in an electric bell?
The core of an electromagnet or an electric bell is made up of soft iron and not steel because
The incomplete diagram of an electric bell is given in the figure. Draw winding of coil on the core and complete the electric circuit in the diagram
In an electric bell, when the electromagnet pulls the iron strip, it also breaks the circuit. The current through the coil stops flowing. In this case, will the coil remain an electromagnet? How does an electric bell ring then?
