प्रश्न
Predict the direction of induced current in the situation described by the following figure.
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:
There won't be any induced current because the loop is perpendicular to the magnetic field lines.
No current is induced since the field lines are lying in the plane of the closed loop.
