MHT CET 2024 Physics question

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

(A)magnetic flux is zero and induced e.m. f. is maximum
(B)magnetic flux is maximum and induced e. m. f. is zeroCorrect
(C)both magnetic flux and induced e. m. f. are maximum
(D)both magnetic flux and induced e. m. f. are zero

Answer: (B)

Solution

When the plane of the coil is perpendicular to the field, the area vector is parallel to , so and the flux is maximum. The induced emf is zero at because the coil's sides are moving parallel to the
