The [[Lorentz Force Law]] describes the effects of a charged particle moving in a constant magnetic field. The simplest form of this law is given by the vector equation.
<math display="block">\mathbf{F} = Q \left(\mathbf{v}\times\mathbf{B}\right)</math>

where 
* {{math|'''F'''}} is the force acting on the particle.
* {{mvar|Q}} is the charge of the particle,
* {{math|'''v'''}} is the velocity of the particle, and
* {{math|'''B'''}} is the magnetic field.

The vector {{math|'''F'''}} is perpendicular to both {{math|'''v'''}} and {{math|'''B'''}} according to the [[right hand rule]].
