 The Lorentz force 
  It seems reasonable, therefore, that the force exerted on the wire when it is placed in a magnetic field is simply the resultant of the forces exerted on these moving charges. 
  This formula implies that the magnitude of the magnetic force exerted on a moving charged particle is the product of the particle's charge, its velocity, the magnetic field strength, and the sine of the angle subtended between the particle's direction of motion and the direction of the magnetic field. 
  The magnetic force, however, is perpendicular to both the local magnetic field and the particle's direction of motion.
