text: 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.
  where 
  *  is the force acting on the particle.
  *  is the charge of the particle,
  *  is the velocity of the particle, and
  *  is the magnetic field.
  The vector  is perpendicular to both  and  according to the right hand rule.
