Magnetic Force on a Moving Charge:
- The force on a moving charge in a magnetic field is equal to the cross product of the particles velocity with the magnetic field times the magnitude of the charge.
- The direction of the Magnetic Force is always at right angle to the plane formed by the velocity vector v and the magnetic field B. (Right-hand rule)
- The Magnetic Force depends upon the size of the charge q, the magnitude of the magnetic field B, and how fast the charge is moving v perpendicular to the magnetic field (equivalently, the size of v and the component of B perpendicular to the direction of the moving charge).
