MAGNATIC FORCE

Attraction or repulsion that arises between electrically charged particles that are in motion. While only electric force exist among stationary electric charges, with both electric and magnetic force exist among moving electric charges.The magnetic force between two moving is the force exerted on one charge by a magnetic field created by other.This force is zero if the second charge is travelling in the direction of the magnetic field due to the first and is greatest i it travels at right angle to the magnetic field. Magnetic force is responsible for the action of electric motor and the attraction between magnet and iron.
