This sample is a double-sided convex ring ferrite magnet with various isotropic grades, belonging to a customized sintered magnet. The surface magnetic field strength is not high, only 500 to 600 Gauss, and it adopts radial multipole magnetization, which can be 18 poles, 20 poles, and 22 poles. It is mainly used in motors, sensors, and electrical appliances. Compared to traditional planar ferrite magnets, double-sided convex ring ferrite has a larger effective magnetic field area, Provide higher magnetic field output and better energy conversion efficiency. It also has lower magnetic field leakage and radiation interference, which helps to improve the performance and anti-interference ability of the equipment.
