The global permanent magnet market is dominated by rare earth magnets based on the Nd2Fe14B phase, which accounts for over 60% of total magnet sales. The historical development of rare earth magnets is overviewed in this article, as well as the current status of material development, processing technologies, market drivers, and an alternative approach to […]

Rare Earth Permanent Magnets have revolutionized the world. Their numerous applications have served a wide variety of industries, and further innovations are being developed today. Learn more about the history of rare earth permanent magnets and where they might take us in the future!

Magnet Applications, Engineering & Quality Manager, Robert Fredette, and Technical Advisor, Dr. John Ormerod, collaborate with others on an article from Science Direct, “Fabrication of highly dense isotropic Nd-Fe-B nylon bonded magnets via extrusion-based additive manufacturing.”

Magnet Applications Senior Technology Advisor, Dr. John Ormerod, was again invited to speak at this years Magnetics 2018 Conference.

The use of cylindrical magnets in rotary position magnetic sensors is ideal to generate the field components required for proper operation. There are two types of field orientations used for this purpose and they are specific to the type of IC used in the application. The magnet can be magnetized either diametrically, or axially. For […]

With four major types of permanent magnet materials available, device designers are faced with a bewildering range of options. Permanent magnets have special requirements for assembly and use, and often magnetic parameters may not be a designer’s main area of expertise.

Additive manufacturing allows for the production of complex parts with minimum material waste, offering an effective technique for fabricating permanent magnets which frequently involve critical rare earth elements.

This articles summarizes original research on the successful fabrication of NdFeB bonded magnets using a binder jetting process and the resulting magnet properties. Published by The Minerals, Metals & Materials Society.

What issues are involved in post assembly magnetization? In this presentation from Dr. Chris Riley you can learn about magnetizing systems and fixture design with examples.
