Question

Motional e.m.f induced in a coil is dependent on?

Options
  • A

    Magnetic field

  • B

    Orientation

  • C

    Length

  • D

    All of these

Explanation

The factors on which 'Motional emf' depends are nothing but, the 'magnetic field, velocity, and length of the rod'.

Motional EMF depends on magnetic field strength (B), length of conductor (l), velocity (v), and the sine of the angle between velocity and magnetic field (θ).

Motional EMF depends on magnetic field strength (B), length of conductor (l), velocity (v), and the sine of the angle between velocity and magnetic field (θ).
