A rectangular coil ABCD is rotated anticlockwise with a uniform angular velocity about the axis shown In the fig. the axis of rotation of the coil as well as the magnetic field `B` are horizontally.the induced emf in the coilwould be minimum when the plane of the coil

Options

A. The plane of the coil is horizontal
B. The plane of the coil makes an angle of `45^@` with the direction of the magnetic field
C. The plane of the coil is at right angle to the magnetic field
D. The plane of the coil makes an angle of `30^@` wiht the horizontal

Answer

A

Explanation

When the plane of the coil will be horizontal maximum flux will pass through the coil.
