Neodymium – The Most Commonly Used of Rare Earth Magnets Neodymium is the most commonly used of the rare earth magnets because of its strength and affordability. Rare earth magnets are strong, permanent magnets which do not easily lose their magnetism and is the reason they are considered permanent. Developed in the 1970s and 1980s, rare earth magnets are the strongest type of permanent magnet that is made. Rare earth magnets are composed of alloys of rare earth elements, including iron, nickel and cobalt. These magnets are usually plated or coated to protect them from breaking and chipping because they tend to be brittle, making them more vulnerable to corrosion. The two types of rare earth magnets are Neodymium and Samarium-cobalt. Neodymium is the strongest of all permanent magnets, including samarium-cobalt, alnico and ferrite. Although the classification of rare earth magnet makes it sound unique and difficult to find, the truth is that the elements it is composed of – neod Less
