Calculations based on Motional Electromotive Force

Motional Electromotive Force

The magnetic force exerted on the charges in a moving conductor will generate a motion that can be associated with a voltage. The generated voltage can be seen to be the work done per unit charge.

Motional EMF = velocity of the charge carriers *Magnetic field * length of the wire

The equation is:

EMF = v B L

Where:

EMF: Electromotive force

v: Velocity of the charge

B: Magnetic field

L: Length of the wire where the charge is moving
