When
electrons move at right angles to a constant magnetic field, the magnetic field
produced by the movement of the electrons distorts the main field which is in a
state of tension. Consequently the main field, in trying to return to a state
of stability, will exert a force on the electrons. If the electron path is
through a conductor then this force will be transferred to the conductor. The
force will act in a direction perpendicular to both the direction of electron
flow and the magnetic field. The magnitude of the force varies directly with
the flux density (B) of the field, the rate of flow of the electrons that is
the current (I) and the length of the electron path of the field (L).
