A rectangular coil ABCD is rotated anticlockwise with a uniform angular velocity about the axis shown in diagram below. The axis of rotation of the coil as well as the magnetic field B are horizontal. The induced e.m.f. in the coil would be maximum when

A

The plane of the coil is horizontal

B

The plane of the coil makes an angle of `45^(@)` with the magnetic field

C

The plane of the coil is at right angles to the magnetic field

D

The plane of the coil makes an angle of `30^(@)` with the magnetic field

Text Solution

Verified by Experts

The correct Answer is:
A
`e=e_(0)sinomegat=e_(0)sintheta`
When `theta=90^(@)`
i.e. plane of coil will be horizontal.
