Question

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 are horizontal. The induced e.m.f. in the coil would be maximum when :

  1. the plane of the coil is vertical.    
  2. the plane of the coil makes an angle of 45degree with the magnetic field.    
  3. the plane of the coil is parallel to the magnetic field.    
  4. the plane of the coil makes an angle of 30degree with magnetic field.    

The correct answer is: the plane of the coil is parallel to the magnetic field.
