What is the Effect of Heating Neodymium Magnets: Reversible vs. Irreversible Field Loss

A Neodymium magnet may be used to supply a triggering field for a magnetic sensor.  At various times of operation, the magnet may be exposed to a temperature which reduces the magnetic field to a level which the sensor will not be triggered.  Other than during the high temperature exposure, the magnet will supply a sufficient field to trigger the sensor.  The magnet does not totally demagnetize nor does it suffer lasting effects from the high temperature exposure…
