Detailed explanation-2: -The force exerted by a magnet on the magnetic material is called magnetic force and magnetic effect.
Detailed explanation-3: -Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.
