It belongs to the permanent magnet, and the surface magnetic force is about 1100 gauss.
The application of 10mm thick rectangle ferrite magnet:
Because ferrite is resistant to oxidation and corrosion and high temperature, the block magnet is commom to widely used in auto repair tools, mechanical equipment, Industrial equipment, personal DIY and so on.
