A coil of area A is placed in the X-Y plane. A uniform magnetic field `B_0hati` established. The emf induced in the coil is ____

A

clockwise

B

anticlockwise

C

zero

D

depends on the value of A

Text Solution

Verified by Experts

The correct Answer is:
C
The angle between area vector `vecA` of the coil and `vecB` is `90^@`. So the flux linked with the coil
`phi=AB cos 90^@`
`therefore phi=0`
`therefore` Induced emf `epsilon=0`
