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.
