Lenz's law gives:...

Lenz's law gives:

A

the magnitude of the induced emf

B

the direction of the induced current

C

both the magnitude and direction of the induced current

D

the magnitude of the induced current

Text Solution

Verified by Experts

The correct Answer is:
B
According to Lenz's law, the direction induced current is always in such a direction that it opposes the cause, due to which it is produced.
