    • Why are Samarium Cobalt and Neodymium Magnets Called “Rare Earth” Magnets?

      There are seventeen rare earth elements – fifteen of which are lanthanides and two of which are transition metals, yttrium and scandium – that are found with lanthanides and are chemically similar. Samarium (Sm) and Neodymium (Nd) are the two most commonly used rare earth elements in magnetic app...

    • The History Neodymium

      Neodymium: A little background Neodymium was discovered in 1885 by Austrian chemist Carl Auer von Welsbach, though its discovery brought about some controversy — the metal cannot be found naturally in its metallic form, and must be separated from didymium. As the Royal Society of Chemistry notes,...

    • What Types of Metals are Attracted to Neodymium Magnets?

      We all know that magnets attract each other at opposite poles and repel at like poles. But exactly what types of metals do they attract? Neodymium magnets are known as the strongest magnet material available and have the highest holding strength to these metals. They are called ferromagnetic meta...
