In an a. c. generator, when the plane of the coil is perpendicular to the magnetic field

Options

  1. Amagnetic flux is zero and induced e.m.f. is maximum.
  2. Bmagnetic flux is maximum and induced e.m.f. is zero.
  3. Cboth magnetic flux and induced e.m.f. are maximum.
  4. Dboth magnetic flux and induced e.m.f. are zero.

Correct answer

B. magnetic flux is maximum and induced e.m.f. is zero.

Step-by-step solution

Magnetic flux, ( _B=B A ) where ( ) is the angle between normal to the plane of the coil and magnetic field. Induced emf, ( =B A ) Here, ( =0^ ) ( ) Magnetic flux is maximum and induced emf is zero.
