A magnet is taken towards a coil [i] Rapidly [ii] Slowly Then the induced emf is-
Text Solution
Verified by ExpertsThe correct answer is:
A
When the magnet is brought near a coil rapidly, then the number of magnetic fields passing through the coil changes more rapidly, and hence more emf is induced in the coil.
When the magnet is brought near a coil slowly, then the number of magnetic fields passing through the coil changes slowly, and hence less emf is induced in the coil.
