Magnetism

The magnetic force exerted on a moving particle in a magnetic field is the cross product of the magnetic field and the velocity of the particle, multiplied by the charge of the particle.

Because the magnetic force is perpendicular to the particle's velocity, this causes uniform circular motion. That motion can be explained by ..............................

The magnetic potential energy is the opposite of the dot product of the magnetic field and the dipole moment.
