Looking for advice on how to read and use these demagnetization curves?  Our article on Magnet Grades includes a good description of what the curves mean and how they are created in the first place.  Our in-depth article on Temperature and Neodymium Magnets shows how to use these curves to estimate the maximum operating temperature of a particular magnet.
