Application: all kind of motors, home appliances and other permanent magnet motors, etc.
A ferrite arc magnet is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe2O3, rust) blended with small proportions of one or more additional metallic elements, such as strontium, barium, manganese, nickel, and zinc.[1] They are ferrimagnetic, meaning they can be magnetized or attracted to a magnet. Unlike other ferromagnetic materials, most ferrites are not electrically conductive, making them useful in applications like magnetic cores for transformers to suppress eddy currents.[2] Ferrites arc magnet can be divided into two families based on their resistance to being demagnetized (magnetic coercivity).
