Question

What is motional emf? State any two factors on which it depends.

What is meant by Motional emf?

Answer 1

Induced EMF by the change of area of the coil linked with the magnetic field.

e = Bvl

It depends on

1) Magnetic field

2) Velocity of conductor

3)  Length of conductor

Answer 2

Emf is induced in a conducting rod when it moves in a region of the magnetic field.

It is calculated by

E = νBl

Where B = magnetic field
l = length and
ν = velocity

It depends on -

1. Magnetic field
2. Velocity of conductor
3. Length of conductor
