Lenz's Law
This law is mostly used to find the direction current induced in a circuit. According to this law the polarity of e.m.f. induced in the circuit is such that it opposes or checks the variation in magnetic flux responsible for it. It we move north pole of a bar magnet towards coil, then magnetic flux linked with the coil changes (i.e., increases). Due to this current is induced in the coil in anticlockwise direction. The magnetic moment related with the induced current has north polarity towards the north pole. If we move away the bar magnet then magnetic moment has south polarity.

Lenz's law obeys the law of conservation of energy.
Lenz's law is used to find the direction of:

A

Electric field

B

Force

C

Induced current

D
