Many customers are looking for the demagnetization curve of ferrite, such as Y30 demagnetization curve, Y33 demagnetization curve, etc. The following permanent magnet supplier Courage Xiaofu has compiled a report on the demagnetization of permanent magnet ferrite (Y10 Y25 Y30 Y33 Y30BH Y35) The graph, I hope it helps you.
Ferrite Y25/Y30/Y30BH/Y35 demagnetization curve

At what degree do ferrite magnets demagnetize?
Generally, the maximum working temperature of ferrite is 250℃; but most of the losses in the range of 250℃ will recover when it drops to room temperature.
The above is the introduction of the demagnetization curve of the common performance grades of sintered ceramic ferrite magnets, compiled and edited by the neodymium magnet manufacturer Courage Xiaofu.
