Neodymium Magnet Strength

Neodymium Rare Earth Magnets are the strongest commercially available permanent magnets in the world.  Originally invented by General Motors and Sumitomo Special Metals in the early 1980s, Neodymium Magnets are a key component in mobile phones, computers, wind turbines, and modern cars.  The list of applications is nearly endless. As the name suggests, the prime…

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…

The Necessity of a Global Strategy for Plastics Waste Since 1950, it is estimated that 8.3 million metric tonnes of virgin plastics have been produced.  Of this, 6.3 million metric tonnes has become waste, with 9% being recycled and 12% incinerated.  This leaves 79% that is accumulated in landfills or the natural environment. The report…

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…

Magnetic Separator

Magnetic Separator Fact and Fiction Trying to ascertain what and whose Magnetic Separator will provide the best metal separation can be difficult.  Often, the decision is made even more difficult with claims and counterclaims about levels of Gauss and what the Magnetic Separator can actually capture.  In this blog, we try to dispel those Magnetic Separator myths.…

9th of 10 Magnetic Separation Myths In school science, we learn about magnetism by playing with small permanent magnets.  It is fun, seeing how iron filings are affected by the magnetic field.  Our bodies are also constantly exposed to the Earth’s Magnetic Field. So how can Magnets be dangerous? In the 1980s, the concept of permanent…

A common question asked by users of Magnets, Magnet Assemblies, and Magnetic Separators is whether a Magnetic Field can be blocked in the same way that lead blocks radiation.  This can be an important issue when considering the location of a Magnet and Magnetic Product and whether it is near instrumentation, control panels, or is…

6th of 10 Magnetic Separator Myths On a typical Cartridge or Tube Magnet, the magnetic field on the surface is not even along the whole length.  As shown on the photograph, magnetically attracted materials agglomerate at specific points along the length.  So why is that? A Cartridge or Tube Magnetic Separator is constructed by placing…

3rd of 10 Magnetic Separator Myths On a regular basis, we will receive an enquiry requesting a Magnetic Separator of a specific size.  However, it is only when the enquiry also requests a specific gauss figure that it all starts becoming a little complicated. Frequently, the gauss figure has been added with little understanding of the meaning…

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…
