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…

Car Dashboard Magnetic Sensors

Sensors are used everywhere from vehicle engine management systems to Smartphones determining if the flip cover accessory is closed. Modern everyday life would be very different without sensors and the operation of many of these sensors rely on magnetism. As products evolve, so have the range and specification of sensor magnets. A magnetic sensor converts…

Neodymium Magnet Damage From High Temperatures If a Neodymium Rare Earth Tube Magnet is put into a red-hot fire, then it would not be surprising if the magnetic properties are destroyed.  However, what if the same Tube Magnet is just exposed to steam being flushed through a pipeline system to clean the pipes? Tube Magnets…

2nd of 10 Magnetic Separator Myths A client has a metal contamination problem and needs to install the most suitable magnetic separation.  The metal is small and so they believe that a Magnetic Separator with Rare Earth Magnets is what they need as this produces the strongest magnetic field.  So he picks up the phone…
