In the above question if the coil rotates with a constant angular velocity `omega`, the `EMF` induced in it

A

(a) is zero

B

(b) changes non-linearly with time

C

(c ) has a constant value `= Banomega`

D

(d ) has a maximum value `= Banomega`

Text Solution

Verified by Experts

The correct Answer is:
B, D
(b,d):
if the normal to the plane of the coil makes an angle `theta` with the direction of `B`, the flux linked with the coil is
`phi = Ban cos theta`
`= Ban cos (omegat)`
`e.m.f. = e = (-dphi)/(dt) = Banomegasin(omegat)`
