Radially magnetised magnets are rare due to a complex manufacturing process. Radially magnetised magnets are mostly used in motors and generators, as well as in free energy experimentation and rare earth permanent frictionless bearings.
This cylindrical Neodymium magnet has been radially magnetised with the south polarity on the inside and north on the outside. The outer diameter is 25mm and inner diameter is 15mm with a stainless-steel ring on the outside.
Radial Ring Magnets are manufactured with the north and south pole on the outside diameter (OD) and inside diameter (ID). These can be used as motor magnets, sensor magnets, and any applications were multiple or single poles are required on the OD or ID of the magnet.
Radial Ring magnets can be manufactured as a single magnet but with limitation on size. Single radial ring magnets are limited to 25mm on the OD, 15mm on the ID, and approximately 10mm on the thickness. These single pieces can be magnetized with the same pole all around the OD, or alternating poles on the OD. Radial Rings made in a single piece usually include separate tooling charges for manufacturing and the magnetizing fixtures. neodymium segmented radial rings n50
Radial Ring magnets can also be manufactured in magnet arc segments. These segmented radial rings allow for larger sizes on the OD, but the ID is limited to 15mm or larger on the ID. These radial rings made with magnet segments can be magnetized with the same pole all around the OD, or alternating poles on the OD. Radial Rings made with segments usually include tooling charges for manufacturing only and will include a non-magnetic ring on the OD or ID to assist with assembly of the magnet arc segments.
MPCO Magnetics has been assisting Corporate customers for many years with their custom radial ring magnet and magnetic assembly applications.
