Provided is a high temperature-resistant radially oppositely polarized magnetic ring, consisting of, in order from inside out, a magnetic ring body, an insulating coating layer, and a high temperature-resistant coating layer. The magnetic ring body is a neodymium magnetic ring. The insulating coating layer is an epoxy coating layer. The high temperature-resistant coating layer is an organosilicon coating layer. The epoxy coating layer has a thickness of 100 to 200 micrometers. The organosilicon coating layer has a thickness of 100 to 200 micrometers. The high temperature-resistant radially oppositely polarized magnetic ring of the present invention has the following technical effect: even if the magnet is severely corroded, the magnetism does not weaken. |
