They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.

Demagnetization randomizes the orientation of magnetic dipoles. Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal. Demagnetization occurs naturally over time.

To demagnetise a permanent magnet place it inside a solenoid, pointing East-West, through which an alternating current is flowing. While the current is still flowing, the small atomic magnets present in the permanent magnet get disoriented and hence the permanent magnet gets demagnetised.

three properties

three types

The three types of magnets are temporary, permanent, and electromagnets. Magnets are categorized by their source of magnetism. Temporary magnets become magnetized in the presence of a magnetic field. They lose their magnetism gradually, when the magnetic field is removed.

A lodestone is a naturally magnetized piece of the mineral magnetite. They are naturally occurring magnets, which can attract iron. The property of magnetism was first discovered in antiquity through lodestones.

The ends of a magnet are called its poles. One end is called the north pole, the other is called the south pole. If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other.

Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material.

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.

When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).

Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. Magnets attract when a north pole is introduced to a south pole. If like poles are introduced, either north to north or south to south, the magnets repel.

Magnets are always attracted to ferromagnetic substances like iron, cobalt, nickel and the alloys containing them (example: steel). Ferromagnetic materials not only get attracted to magnets, but they can also retain the magnetic properties after the magnet is removed.
