In The Given Figure, The Galvanometer Will Not Have A Deflec...


Options:
A .   the bar magnet is moved in the direction shown
B .   the bar magnet is moved in the opposite direction
C .   the bar magnet is kept stationary 
D .   the wire loop on the conducting cylinder is moved towards the bar magnet
Answer: Option C
:
C

An emf would be induced in the coil if there is a change in the magnetic flux. This can happen if the bar magnet and the coil move relative to each other i.e. if the bar magnet moves towards/away from the coil or the coil moves towards/away from the bar magnet. But if neither the bar magnet nor the coil moves then the induced current is zero.
