Electricity and Magnetism EMF Induced in a Conductor Moving through a Magnetic Field
A
conductor is moved a distance,
The free
electrons in the conductor will experience a force causing
them to move through the conductor. Suppose that a total
charge
The work done by the force F is given by
This work
is equal to the energy given to the charge
and, work done per Coulomb is
the induced emf
If the conductor moves at constant speed, the force F must be equal but opposite to the force acting on it due to the current, I, induced in it.
