Magnetic Design Redesign Cost One of the most important aspects of magnetic design optimizing, is being able to design to cost. Magnets are used for their magnetic properties and its magnetic field. These are affected by many parameters, and some of them are not obvious at all. The best example is the magnet shape, different [...]
Magnets technical information The determining of magnetic properties is often not given its proper place along the development path of a product. These basic but important considerations are commonly considered as features which will adapt themselves into the required format at a later date. This may be true for applications using low coercive materials such [...]
How to Control the Quality of Neodymium Magnets? Permanent Neodymium magnet, chemically known as NdFeB, is known as the most significant magnet material with high performance and are widely applied in many industrial fields. To manufacture the highest quality magnet products, we need to assure the accuracy of: magnetic property, physical dimensions and surface plating. [...]
Wind Power Magnets To that end we have developed a line of permanent magnets exclusively for direct drive, wind power turbine generators. We have produced this grade of material for use in DD PMG's (Direct Drive Permanent Magnet Generators) for small and large size wind turbines from 25 kW to 2.3 MW. DD PMG’s used [...]
Magnetic Theory and Design 1. Can you explain the difference between coercive force and intrinsic coercive force? The intrinsic coercive force is the coercivity of a magnet material in a closed circuit configuration. A closed circuit configuration means the magnet does not have any exposed poles. Some examples of a closed circuit configuration are a [...]
Magnetic Magnetization Patterns Isotropic magnets, such as Bonded Nd-Fe-B, are unoriented and have no preferred direction; therefore it is possible to magnetize them in any direction. Almost all other materials are anisotropic and have a preferred direction of magnetization. They will exhibit the best magnetic properties when magnetized in the direction of the grain. Higher [...]
Researchers Developing Sustainable 3D Printed Super Magnets An additive manufacturing breakthrough coming out of TU Graz in Austria could make it easier to manufacture permanent magnets for small electronic components. A TU Graz team—working in collaboration with the University of Vienna, the Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) and Joanneum Research—has successfully manufactured super magnets using a [...]
Can 3D-Printed Magnets Replace Rare Earth Magnets? Additive manufacturing can turn everyday magnetic material into alternatives for expansive rare-earth magnets. Engineers at the Amess Laboratory’s Critical Materials Institute used laser 3D metal printing to turn permanent magnet material into an economical alternative to more expensive rare-earth neodymium iron boron (NdFeB) magnets. The researchers experimented with [...]
Reconfigurable 3D-printable Magnets with improved maximum energy product In conventional magnets, neodymium with added heavy rare-earths is used in order to induce high output and size reduction. But as deposits of heavy rare-earths such as dysprosium (Dy) and terbium (Tb) are disproportionately distributed, it is important to reduce the amount used due to supply issues [...]

NEODYM alloys are anisotropic material grades. Our NEODYM Alloys made of Neodymium-Iron-Boron Rare-Earth NdFeB Permanent [...]
Here's the Actual Difference Between Paramagnetism and Diamagnetism Paramagnetism and diamagnetism are two distinct types of magnetic properties exhibited by the different elements in nature. Here, we shall learn more about each of them, and find out how they differ from one another. Levitation! The Radboud University Nijmegen, the Netherlands, conducted experiments where water and [...]
Nanocomposite Permanent Magnet Materials Nanocomposite permanent magnet materials, combining magnetically hard and soft phases in nanoscale, is a new permanent magnetic material. Compared with traditional permanent magnetic material, nanocomposite lowers rare earth content and cost, exhibits high coercivity of hard magnetic phase and high saturation magnetization of soft magnetics phase, upgrades in temperature stability, heat [...]
