If North pole of a bar magnet is taken away from a coil, which of the following happens according to Lenz' Law?
Answer & explanation
Correct answer: option 2
As the North pole of the bar magnet is taken away, the induced EMF will be such that it will attract the bar magnet. Therefore, the coil will develop South polarity. With the polarity being South now, the current will be in clockwise direction.
