Magnetism and Magnetic Materials

Magnetism

The Force of attraction acting from a distance is known as Magnetism. Magnetic field is produced by the movement of electrically charged particles. North and south poles are two poles in a magnet. Opposite poles  of two magnets will attract each other and like poles will repel each other. In magnets and electric currents, magnetism symbolizes to the attraction of iron and other metals. In everyday life paramagnetic, diamagnetic, and antiferromagnetic materials are often described as non-magnetic as the force of a magnet on is usually too weak to be felt, and can be detected only by laboratory instruments.
