Two coils A and B of insulated wires 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 (i) a current is passed through coil B by plugging the key, and (ii) the current is stopped by removing the plug from the key? Explain your answer mentioning the name of the phenomena involved.

If the current is passing through coil b.A induced current will be formed in the Coil 'A'.this is shown by deflection of needle in the galvanometer.this phenomenon is known as electro magnetic induction.it is used mainly in generators
