发明名称 Permanent magnet temporary demagnetization temperature rise technique and their application for soldering
摘要 A method for raising a demagnetization temperature of a permanent magnet is disclosed. The method provides a ferromagnetic arrangement around the magnet to increase demagnetization thresholds for the duration of soldering, or any other process requiring high temperatures. Using the method disclosed, it is possible to apply high levels of heat directly to permanent magnets without demagnetization, and more particularly to create permanent magnetic assemblies fit for any environment.
