the number of magnetic lines of force also
changes. Which of the following condition is
correct
(a) lines of force minimum but induced e.m.f. is
zero
(b) lines of force maximum but induced e.m.f. is
zero
(c) lines of force maximum but induced e.m.f. is
not zero
(d) lines of force maximum but induced e.m.f. is
also maximum

Answer:
The coil of a dynamo is rotating in a magnetic field. The developed induced e.m.f. changes and the number of magnetic lines of force also
the correct option is b. that is lines of force maximum but induced e.m. f. is zero,
becoz,
e ∝ dФ / dt
if Ф is maximum then e is minimum.
other options are not suitable for the developing the induced e.m.f. changes and numbers of magnetic feild line.
