A current I from A toB is increasinginmagnitudes as shown in figure. What is the direction of induced current in the loop.

Answer»

Solution :
The current I will produce a magnitudefield B in upward direction in theregion in which COIL is PLACED.
Since, the current is increasing in magnitude , B will also increase with time, subsequently increaseing flux.
To counter the increasing flux , incduce field `B_i` is produced opposite to direction b. POINTING right hand thumb in the direction of `B_i` and curling fingers, we can find out the direction ofinduced current to be clockwise.
