Induced current should be in anticlockwise direction, so that upper face becomes south pole.
(b) Induced current should be clockwise so that upper face becomes south pole.
( c) Flux is increasing in the inward direction, so induced current should be in anticlockwise direction. It will oppose the increase of flux .
(d) Flux is decreasing in the upward direction, so induced current should be in anticlockwise direction. It will oppose the decrease of flux .
