What is the maximum magnetic field strength of ferrite magnet?
Permanent ferrite, also known as ferrite steel, is the small black magnet we usually see. The main raw materials are iron oxide, barium carbonate or strontium carbonate. After magnetization, the residual magnetic field is very strong and can be maintained for a long time. It is usually used as permanent magnet material.
Ferrite magnets are mostly used in loudspeakers, as shown in the figure below.
What is the highest magnetism of a ferrite magnet?
The highest surface magnetism of ferrite magnet reaches the peak value at about 1700gs, which will not exceed 2000 due to the material relationship. Generally, the ferrite magnetism purchased by customers is about 1000-1200gs. Of course, the measurement result is related to the size of the magnet and the measuring instrument Gauss meter. I used the Japanese Gauss meter to measure the surface magnetism of the radial 8-pole ferrite magnet, which is more than 1900. Maybe the domestic Gauss meter can measure the surface magnetism, which is more than 1700-1800.
