प्रश्न

Two coils A and B of insulated wire are kept close to each other. Coil A is connected to a galvanometer while coil B is connected to a battery through a key. What would happen if: 

a current is passed through coil B by plugging the key?  

Explain your answer mentioning the name of the phenomenon involved.

उत्तर

 If current is passed through coil B by plugging key, the galvanometer pointer will move to one side. The movement of galvanometer pointer shows that a current is induced in the coil.
