This kind of magnets are widely used in synchronous motor, toy motor, sensor, electric instruments and so on. Especially, magnetic field of anisotropic ferrite ring magnet can reach 1600Gs t0 1700Gs which meet the Japanese standard TDK-FBSH. We have already some mouls of different sizes, but your own design is also welcome.
