Since ferrite magnets are widely used, they must have their reasons and advantages. The following author will take you to understand. Ferrite magnet is a ferromagnetic metal oxide. In terms of electrical properties, it has much greater resistivity and dielectric properties than metals, alloys and other materials. In addition, it exhibits higher magnetic permeability at high frequency, so it is widely used in the field of high frequency and weak electricity, and belongs to the composite oxide of ferric oxide and one or more metal oxides. At the same time, because of the 800-1000 Gauss magnetic force and the density of 5 (g/cm3), it can be used in sound boxes, speakers and other equipment. The above is the introduction of ferrite magnets, do you understand?
