Abstract
When it is not possible to place magnets into their final assembly before magnetizing them, the performance of high energy magnetic materials having a nonlinear demagnetization characteristic at room temperature is improved by heating the magnetic material, magnetizing the heated magnetic material and then placing the resulting heated magnetic into its final assembly and letting it cool to room temperature.
