A force on moving charges particles in the presence of magnetic B and electric fields E. The electromagnetic field tensor in MKS is given by
(1)

(2)

(3)

(4)

(5)

(6)

so the Lorenz force is
(7)

(8)

where q is the charge on a particle, v is its velocity, is the electric potential, and A is the magnetic vector potential.
For small speeds (i.e., ) in MKS,
(9)

(10)

(11)

so
(12)

giving
(13)

Similarly, in cgs,
