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

Options

  1. AThe number of turns in the coil
  2. BThe medium of the core of the coil
  3. CThe strength of the magnet
  4. DThe resistance of the coil

Correct answer

D. The resistance of the coil

Step-by-step solution

The magnitude of induced emf is given by, e = N d ϕ d t = N B d s d t Which depends upon the number of turns (N), magnetic field intensity (B) which depends upon the medium, rate of change of area d s d t which depends upon insertion speed of magnet. It is independent of resistance of the coil.
