Magnetic Force Magnetic fields exert force on moving charges (the magnetic force) The direction of the magnetic force is –Perpendicular to the direction of movement –Perpendicular to the direction of magnetic field The magnetic force exerted on a charge depends on: –The magnitude of the moving charge (q) –The speed of the moving charge (v) –The magnitude of the magnetic field (B) –The angle (  ) between v and B To calculate magnetic force on a moving charge: or
