When a magnet is taken towards a coil, the induced e.m.f. depends on
Options
(a) the number of turns in the coil
(b) the speed of the magnet
(c) the resistance of the coil
(d) the magnetic moment of the magnet
Correct Answer:
the speed of the magnet
Explanation:
Induced e.m.f. depends on rate of change of flux linked with a coil. This, is turn, depend on the speed of the magnet taken towards the coil.
