Detailed Product Description
This magnet does have one major advantage over other Rare Earth magnet materials which is that the Isotropic nature allows it to be magnetised in any direction. It is also possible to have complex multiple pole magnetisation making it an ideal choice for the computer peripheral industries for applications such as small precision motors. Radial and multiple pole magnetisation requires special magnetising fixtures.
