Q110 / 160 · JIPMER 2011 · Physics

Induced emf in the coil depends upon

  • A
    conductivity of coil
  • B
    amount of flux
  • Correct answer
    C
    rate of change of linked flux
  • D
    resistance of coil

Solution

According to Faraday's law, "the induced emf in a closed loop equals the time rate of change of magnetic flux through the loop". i.e., $e=-\frac{d \phi_B}{d t}$ Hence, induced emf in a coil depends on rate of change of flux.

Hence, the correct answer is option: 'C'.
