Magnetic force is an attraction, or repulsion that arises between opposite magnetic poles. The motion of charges causes magnetic force, which is a result of electromagnetic force. A charged body exerts electrostatic force, while a magnet exerts magnetic force. Magnetic forces do not cause this phenomenon as there is no magnetic effect observed.
