Ferrite permanent magnet(ceramic ferrite) also known as ferrite magnet steel, is usually we see the small black magnet. Its main raw materials are iron oxide, barium carbonate or strontium carbonate. When magnetized, the residual magnetic field is strong and can be retained for a long time. It is usually used as a permanent magnet material.
What is the highest magnetic value of a ferrite magnet?
Ferrite magnet surface magnetic highest about 1700GS will reach the peak, due to the relationship between materials so will not exceed 2000, usually customers use the purchase of ferrite magnetic around 1000-1200gs in the majority. Isotropic ferrite is like this at 500 Gauss to 700 Gauss.
Of course, this measurement result is related to the size of the magnet, and also related to the measuring instrument Gauss meter. Previously, I used the Japanese Gauss meter and the domestic Gauss meter to measure, and the difference between the results was about 200 Gauss.
Our company is a supplier of permanent magnets from China, which can provide a variety of isotropic and anisotropic ferrite magnets, such as ordinary ferrite circular disc magnets, arc ferrite magnets, ring ferrite magnets, square block ferrite magnets, and multipolar injection molding ferrite magnets. They are sold directly by manufacturers at a lower price. Welcome to consult!
