Question 266: Electromagnetic Induction

Question

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

Accepted Answer

When the plane of the coil in an alternating current (a.c.) generator is perpendicular to the magnetic field, the magnetic flux through the coil is maximum, because the area vector of the coil is aligned with the magnetic field lines.
At this position, the rate of change of magnetic flux, which is responsible for inducing the electromotive force (e.m.f.), is zero. Therefore, the induced e.m.f. at this point is zero.
Thus, the correct option is:
Option B: magnetic flux is maximum and induced e.m.f. is zero.

Answer

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

Answer

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

Answer

both magnetic flux and induced e.m.f. are maximum.

Answer

both magnetic flux and induced e.m.f. are zero.
