Question
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 z
- The plane of the coil is horizontal
- The plane of the coil makes an angle of 45° with the magnetic field
- The plane of the coil is at right angles to the magnetic field
- The plane of the coil makes an angle of 30° with the magnetic field
The correct answer is: The plane of the coil is horizontal
Emf = 
e will be maximum when q is 90o i.e. plane of the coil will be horizontal.
