Explain the magnetic effect of current with help of diagram. Write the name of twoapparatus working on this principle. Explain the working of electric bell by drawing itslabelled diagram
Answers
An electric bell contains an electromagnet, consisting of coils of insulated wire wound round iron rods. When an electric current flows through the coils, the rods become magnetic and attract a piece of iron attached to a clapper. The clapper hits the bell and makes it ring.
When the bell is pressed, the contact screw touches the iron strip and the circuit is completed. ... The electromagnet becomes magnetised and the soft iron armature is attracted towards the electromagnet
