All matter exhibits magnetic properties when placed in an external magnetic field. Opposites attract. Most people know that iron is attracted to magnets, while other metals like gold and silver are not. Demagnetizing a magnet is also possible. 56. When there are no free moments, the magnetization is produced by currents of the electrons in their atomic orbits. (The samarium-cobalt and neodymium-iron-boron families are collectively known as the rare-earths). No matter what pole of the permanent magnet is extended toward the iron, the iron will magnetize in such a way as to be attracted toward the magnet: Referencing the natural magnetic properties of iron (Latin = “ferrum”), a ferromagnetic material is one that readily magnetizes (its constituent atoms easily orient their electron spins to conform to an external magnetic field force). • When the N-pole of a magnet is placed near the S-pole of another magnet than it will attract the south pole. Posted on July 3, 2017. metals that are magnetic. When a ferromagnetic material is brought close to a magnet, the poles of the individual atoms of the material align along the magnetic field lines. 57. We all know that magnets attract each other at opposite poles and repel at like poles. List of Magnetic Materials. All the substances other than iron, nickel, and Cobalt are non-magnetic substances for example plastic, rubber, water, etc are nonmagnetic materials.
