If a magnet is plugged into a coil, then the magnitude of induced emf does not depend upon

Options:

Answer:
D
Solution:

The magnitude of induced emf is given by,e=Ndϕdt=NBdsdt

Which depends upon the number of turns (N), magnetic field intensity (B) which depends upon the medium, rate of change of areadsdtwhich depends upon insertion speed of magnet. It is independent of resistance of the coil.
