The History of Neodymium Magnets

The origin of the neodymium magnet dates back to 1885 when Carl Auer von Welsbach, an Austrian scientist and inventor, separated didymium into the new separate elements neodidymium (“new didymium”) and praseodidymium (“green didymium”).  In time, the element names would change to neodymium and praseodymium. Neodymium (Nd) is the fourth member of the lanthanide ‘rare-earth…

Magnets and the Curie Temperature

Curie Temperature

The term “Curie temperature (Tc)” or “Curie point” gets frequently mentioned when discussing magnets and magnetic properties.  The Curie temperature relates to the maximum temperature a material can reach before losing its magnetic properties.  On reaching a magnetic material’s Curie temperature, the spontaneous magnetisation in the material drops to zero.  At this point, the material…

Permanent Magnet Motors Providing Key Benefits

White drone motor close up on a black background

Permanent magnet motors are electric motors using permanent magnets in addition to windings.  Such motor designs are more efficient than induction motors or motors with field windings for certain high-efficiency applications such as electric vehicles and small electric motors such as found on drones and in car windshield wipers. Both AC and DC motors benefit…

Magnet Comparison: Neodymium and Samarium Cobalt Rare Earth Magnets

Battle of the Rare Earth Magnets

Neodymium Iron Boron NdFeB (i.e. Neodymium) and Samarium Cobalt SmCo are both ultra-strong rare-earth permanent magnets.  Both are brittle in nature and subject to catastrophic damage if subject to severe impact (i.e. dropping).  However, that is where the similarity ends and, when selecting a magnet material for a specific application, our design engineers assess each…
