Question

An induced emf is produced when a magnet is moved into a coil. The magnitude of induced emf does not depend on:

  1. The resistivity of the wire of the coil
  2. The number of turns of the coil
  3. The strength of the magnet
  4. The speed with which the magnet is moved

hintHint:

An induced emf is produced when a magnet is moved into a coil which depends on the i) relative motion between the magnet and the coil conductor, ii) number of turns and iii) strength of the coil.

The correct answer is: The resistivity of the wire of the coil


    The induced electromagnetic field is not dependent on the resistivity of the wire of the coil.
    • An induced electromagnetic field is formed from the relative motion between the magnet and the coil conductor.
    • The strength of the electromagnetic field depends on the number of turns and the strength of the coil.
    • The speed at which the magnet is moved to the coil determines the magnitude of the induced electromagnetic field.

    Assertion (A): When the current in a coil changes, it induces a back emf in the same coil.
    Reason (R): Emf is a measure of the inertia of the coil against the change of current through it.
