# 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.

 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:

## Force = charge x velocity x B-field

For charge q = e = x 10^ C
with velocity v= x 10^ m/s
moving perpendicular to a magnetic field B = Tesla = Gauss
the force is F = x 10^ N.
If the angle between the velocity and magnetic field is degrees
the force is F = x 10^ N.
