Question

A coil of copper wire is connected to a galvanometer. What would happen if a bar magnet is (a) pushed into a coil with its north pole entering first (b) Pulled out of a bar magnet (c)Held Stationary inside the coil. Dont copy because it is nowhere

Answer 1

Answer:

Answer: a.) Current will get induced in the coil

b.) Again, current will get induced in the coil

c.) Current wouldn't get induced

Explanation: In case of a.) And b.) I. E when the movement of magnet occurs, according to Faraday's law of induction ( I. E change in the magnetic field or the number of magnetic lines passing through the coil causes induction of current); there will be deflections in the galvanometer and current will get induced. But in case of c.), the magnet is stationary which means there is no change in magnetic field or the number of magnetic lines passing through it. Therefore there will be no current induced and no deflections will be seen in the galvanometer as well.
