The sample in the main drawing is a ferrite hollow magnetic column with a diameter of 9mm, a hole of 3.6mm and a height of 15mm. There is no injection water impeller. The product performance is Y30BH, with radial magnetization (2-pole or 4-pole), surface magnetic intensity of about 1300 gauss, and no coating. It is mainly used for micro water pump, cooling water pump, bathtub water pump, sewage pump, Submersible pump, Booster pump, etc.
