Ring Magnets with Multi-poles through Diameter

Magnets magnetized through outer and inner diameter with certain poles (minimum width between poles on outer diameter can be 0.8mm)

It has small tolerance (surface gauss of customized fixture ≦3% )and equally distribution of pole width (tolerance of width between poles ≦3%).

The waveform can be divided into sine wave and square ware. Different waveform is suitable for different applications.

Radially Magnetized

Products with N, S poles concentrically distributed
