When most atoms in an object are tiny magnets, it produces an overall magnetic field with a north and south pole. The History of Magnets M. Sagawa; S. Fujimura; N. Togawa; H. Yamamoto; Y.

The History of Magnets

Phy6.org. "The Great Magnet, the Earth." Nov. 29, 2004. (Sept. 5, 2022) http://www.phy6.org/earthmag/dmglist.htm NdFeB magnets can be classified as sintered or bonded, depending on the manufacturing process used. [7] [8] They have replaced other types of magnets in many applications in modern products that require strong permanent magnets, such as electric motors in cordless tools, hard disk drives and magnetic fasteners.

The Nd 2Fe 14B crystal structure can be described as alternating layers of iron atoms and a neodymium-boron compound. [2] The diamagnetic boron atoms do not contribute directly to the magnetism but improve cohesion by strong covalent bonding. [2] The relatively low rare earth content (12% by volume, 26.7% by mass) and the relative abundance of neodymium and iron compared with samarium and cobalt makes neodymium magnets lower in price than samarium–cobalt magnets. [2] All materials undergo this orbital response. However, in paramagnetic and ferromagnetic substances, the diamagnetic effect is overwhelmed by the much stronger effects caused by the unpaired electrons.Potent magnet that can be molded like clay developed".
