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…

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…
