उत्तर

Lenz's law specifies the direction of the induced current in a closed loop. Using Lenz’s rule, the direction of the induced current in the given situation can be predicted as follows:
The current in the inner half of loop-1 will flow clockwise as the rheostat is turned down, weakening the North Pole.
The direction of the induced current is along zyxz.
