D20x5mm With 5mm Countersink Hole Ring Magnet

Neodymium magnet with countersink hole

Neodymium magnets are produced on the basis of Nd-Fe-B alloys and have the highest (BH)max value nowadays. Neodymium ring magnets are circular in shape with a hollow center. Besides the conventional axial magnetized or diametrically magnetized ring magnets, radially oriented ring magnets are also available in YY Magnetics. Neodymium ring magnets are easy to corrode under humid environment and is necessary to covered with a protective coating.
