Technical Breakthrough on Reprocessing NdFeB Scraps

News has come out that technical breakthrough has been made on reprocessing NdFeB magnets scraps. It seems that to find alternative sources for Neodymium magnets can no longer be avoided due to multiple causes including the following: Demand of existing applications and many next-generation technologies -- Although the world has undergone a serious economical crisis [...]

How is Magnet Strength Measured?

A magnet is any object that produces its own magnetic field. The magnet strength of these objects can vary from imperceptibly weak fields to incredibly strong fields, depending on a number of characteristics. Magnets can be classed into two distinct groups: permanent magnets and electromagnets, and non-magnets can be defined as either ferromagnetic, paramagnetic, or [...]

Magnetic Field Viewer Film Paper

Magnetic Field Viewer Film & Paper This same film is used by professionals, like engineers, developers and researchers to find out the magnetic field distribution when a group of magnets are involved. It is also used in the fabrication industry to image the internal defect of a steel part combined with an X-Ray machine. Encased [...]

How Magnetic Field Viewing Film Works?

Magnetic field viewing film (also called magnetic viewing paper) is made of millions of tiny magnetic flakes suspended in clear oil. This oil is then sandwiched between two sheets of plastic. The magnetic viewing film can then be used to “see” the pattern of magnetization. When a magnet is placed under the viewing film, the [...]

Rare earth magnets for fun and profit

One can academically appreciate the fact that every electric motor in the world (not counting a couple of very impractical ones) works because of magnetism. One can reflect on the fact that every transformer uses it, too. CRT monitors, TVs, brushless DC motors, power meters, modern welding gear and engine ignition timing systems, various vending [...]
