Ferrite magnets are sometimes known as ceramic and their key features are that they will operate at high temperatures while being resistant to demagnetization and corrosion without requiring specialist coatings. Ferrite Arc segments are normally used in pairs for motors and generators and are magnetized so that the inner and outer radii are opposites, and so that each segment is the polar opposite of the other. These arc segments would be ideal for making a cheaper alternative for magnetic water conditioning by strapping the arcs around a pipe (maximum diameter 56mm).

Ferrite Arc Magnet for Motor
For general magnet specifications, molds have already been made for production. If you need special shape, please inform us beforehand for the time of making mold. Magnet is a hard sintered product that is economical and durable. The finished product is subject to shape. Residual flux density is based on size and shape. Before design, it must know the size ratio, magnetic direction, and other information firstly. Ferrite arc magnets are a unique shape which are designed especially for motors.
