Q 6.1 (d) Predict the direction of induced current in the situations described by the following Fig. (d)
Answers (1)
Due to the change in the rheostat setting (resistance decreased), the current in the coil (flowing anticlockwise when viewed from left) and hence magnetic flux linked with it, will start increasing. According to Lenz’s law," The induced current in the adjoining coil should be set up in a direction to oppose the increase in magnetic flux linked with the coil." Therefore, the induced current in the adjoining coil will flow in a clockwise direction when viewed from the left i.e., the induced current will flow in the direction zyx.
Hence, the direction of the induced current in the situation described in the figure is z-y-x.
