It also makes the magnet less susceptible to demagnetizing influences. KiloGauss 1 kiloGauss is equal to 1,000 Gauss. Knee (of the demagnetization curve) In the second and fourth quadrants of the hysteresis loop, some materials such as ferrite and rare earth magnets exhibit a distinct "knee" or rapid change in slope of the intrinsic curve. The location of the knee is of interest to designers. If the magnet operates below the knee, irreversible loss of magnetic output occurs. Copyright © Arnold Magnetic Technologies Corporation.
