Lorentz force

In physics, the Lorentz force is the force exerted on a charged particle in an electromagnetic field. The particle will experience an electric force qE and a magnetic force qv × B. Combined they give the Lorentz force equation

where E is the electric field, B is the magnetic field, q is the charge of the particle, v is its current velocity (expressed as a vector), and × is the cross product operator.
