Question

Current from $A blank a n d blank B$ in the straight wire is decreasing. The direction of induced current in the loop, is

Clock-wise
Anti-clock-wise
Changing
Nothing can be said

The correct answer is: Anti-clock-wise

As current is decreasing, magnetic flux linked with the loop in the upward direction (acceleration to right hand thumb rule) is decreasing. Current induced in loop must be anti-clock-wise to oppose the decrease in magnetic flux.
