Radially Oriented NdFeB Magnets are some of the newest materials in the magnetics industry. The technology for producing rare earth ring magnets with radial magnetic fields has been around for decades, however only in recent years has the cost of manufacturing them come to a point where the magnets are an affordable replacement to traditional multi segmented arcs. There are three main manufacturing methods for producing bonded and sintered radial oriented rings:

Anisotropic Pressure Molding

Hot Pressing & Backward Extrusion

Radial Rotating Field Alignment

Each of these methods produces magnets with certain advantages and disadvantages over the others. Please click on the above links to view presentations on each material in order to determine what is best for your particular application.
