Vedclass · Answer

(A) According to Lenz's law,the direction of the induced current in a coil is such that it always opposes the change in magnetic flux that produces it.In the given diagram,the magnetic field is directed into the plane and is decreasing. Therefore,the magnetic flux linked with the loops is decreasing.To oppose this decrease,the induced current in each loop must create an additional magnetic field directed into the plane (to support the existing field).For the outer loop $abcd$,the current must flow in a clockwise direction to produce a magnetic field directed into the plane.For the inner loop $efgh$,the current must also flow in a clockwise direction to produce a magnetic field directed into the plane.Thus,the direction of the induced current in both loops is clockwise.

Two square wire frames $abcd$ and $efgh$ are placed in a uniformly decreasing magnetic field as shown in the figure. The direction of the induced current in both the loops is
