Magnetic Force Calculator

Find the magnetic force on a moving charge or on a current-carrying wire in a magnetic field at any chosen angle to the field lines.

F = q × v × B × sin θ

A magnetic field pushes sideways on moving charge, strongest when motion is at right angles to the field and zero when parallel.
