This kind of magnets are widely used in synchronous motor, toy motor, sensor, electric instruments and so on. Isotropic ferrite ring magnet is available to magnetize with multi poles radially or axially. The surface Guass is about 400Gs to 900Gs accroding to different size. We have already some mouls of different sizes, but your own design is also welcome.
