WebThe rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 57–71). These metals have unusual fluorescent, conductive, and magnetic properties—which make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron. Geologically speaking, the rare ... WebA magnetic field that has two poles, like the field around a bar magnet, is called a "dipole field".
