A rectangular coil ABCD is rotated anticlockwise with a uniform angular velocity about the axis shown in Fig. The axis of rotation of the coil as well as the magnetic field B is horizontal. The induced emf in the coil would be minimum when the plane of the coil

 

• A

  is horizontal

• B

  makes an angle of 45° with the direction of magnetic field

• C

  is at right angle to the magnetic field

• D

  makes an angle of 30° with the magnetic field
