Vedclass · Answer

(C) According to Lenz's Law,the induced current in a loop will always flow in a direction that opposes the change in magnetic flux that produced it.$1$. The outer loop carries a clockwise current,which produces a magnetic field directed into the plane of the loops (using the Right-Hand Thumb Rule).$2$. Since the current in the outer loop is increasing with time,the magnetic flux through the inner loop (directed into the plane) is also increasing.$3$. To oppose this increase in inward magnetic flux,the inner loop must generate an outward magnetic field.$4$. By the Right-Hand Thumb Rule,an outward magnetic field is produced by a counter-clockwise current in the inner loop.

Two different loops are concentric and lie in the same plane. The current in the outer loop is clockwise and increasing with time. The induced current in the inner loop then,is
