Magnetic field effects
A magnet can be partially demagnetized based on the magnetic load placed upon it. This effect is normally studied by looking at the second quadrant of the hysteresis curve of the magnetic material, also referred to as the demagnetization curve. Typically, this is the only section of the hysteresis curve that is reported for a hard magnetic material. This curve shows the response of the magnets delivered flux into the space around it (B) to the demagnetizing force (H) imposed on the magnet. To assess the performance of the magnet material in a given situation, the user should calculate the ratio of B/H (taking care to ensure the conformity of units). Once this ratio is calculated a line is super imposed on the demagnetization curve, as below for a B/H ratio of 0.8 (note that the illustration shows four demagnetization curves to reflect different operating temperatures)
