Magnetic Forces on Moving Charges

The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule. The force is given by the charge times the vector product of velocity and magnetic field. Magnetic interactions with charge Magnetic force applications Bending a charge into a circular path

If the velocity is perpendicular to the magnetic field then the force is given by the simple product:
