Coercivity or Coercive Force

Coercivity is the resistance of a magnetic material to an opposing external magnetic field. There are two different kinds of Coercivity- Hcb and Hcj. The higher the Coercivity number, the higher the magnet’s resistance to the opposing field.Hcj vs HcbHcb is Normal Coercivity and Hcj is Intrinsic Coercivity.The Difference between Hcj and HcbHcb – is called […]

Neodymium vs Ferrite Magnets

A central question that comes up in a magnet trade study is how to decide whether to use a Neodymium magnet or a ferrite magnet for a particular application. A trade study that seems very simple at first glance can quickly become more complex once all the factors are considered. Neodymium vs ferrite magnets? Designers who […]

How Are Neodymium Magnets Made?

Neodymium magnets are made by a sophisticated process that includes some very high-tech metallurgical methods comprising powder metallurgy and advanced process metallurgy.

Dozens of process steps must be followed very precisely to make Neodymium magnets –also known as NdFeB -for the chemical symbols of Neodymium, Iron and Boron.

Apple’s Tim Cook Tells Why Use China Mfg Capabilities

Apple CEO Tim Cook continued his China tour on Wednesday with an appearance at the Fortune Global Forum. He  points out that It’s not so well known that China has become a world center of high-tech manufacturing, and Tim gives the Chinese educational system a lot of credit for that. They have created a class […]
