Functions for an ordered pair of point charges
A charge
subject to an electric scalar potential at due to a point charge at has an electric potential energy of:A charge
subject to a magnetic vector potential at due to a point charge which had a velocity at has a potential momentum of:Lorentz Force for
The Lorentz Force between charges
can be derived from the scalar potential and the vector potential .A charge
which has a velocity of at will experience a Lorentz force due to a point charge at of:The electric field
is:The magnetic field
is:The Lorentz Force can be expressed directly in terms of the potentials:
