Questions
The north pole of a bar magnet is moved swiftly downward towards a closed coil and then second time it is raised upwards slowly. The magnitude and direction of the induced currents in the two cases will be of
detailed solution
Correct option is D
When it is moving towards the coil, the field lines enclosed in it will be increasing (using Lenz’s Law).To counter the change the induced current in the coil will be in anticlockwise direction.When the bar magnet is moving away, field lines will be decreasing and the induced current will be in clockwise direction.Talk to our academic expert!
