Magnet FAQ

What is the maximum magnetic field strength of a ferrite magnet?

Permanent magnet ferrite (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 table magnetic highest about 1700gs peak, because of the material relationship so will not exceed 2000, usually customers use the purchase of ferrite magnetic around 1000-1200gs in the majority. Of course, this measurement result is related to the specification and size of the magnet, as well as the measurement instrument gaussimeter.

Xiaobian has measured an 8-pole radial ferrite magnet, 1900gs by Japanese Gaussian meter, 1700 by domestic Gaussian meter.
