the Lorentz force is the force on a point charge due to electromagnetic fields.

The force F acting on a particle of electric charge q with instantaneous velocity v, due to an external electric field E and magnetic field B, is given by:

where × is the vector cross product. All boldface quantities are vectors. More explicitly stated:

in which r is the position vector of the charged particle, t is time, and the overdot is a time derivative.
