Magnetic Force on Moving Charges and Currents

How a magnetic field pushes on charges in motion and current-carrying wires.

Force on a Moving Charge

F = qvB sinθ

A charge moving through a magnetic field experiences a force perpendicular to both its velocity and the field — this is the basis of the Lorentz force.

Force on a Current-Carrying Conductor

A current-carrying wire placed in a magnetic field experiences a force, given by F = BIL sinθ.
