Knee of the Demagnetization Curve: The point at which the B – H curve creases to be linear. All magnet materials, even if their second quadrant curves are straight line at room temperature,
develop a knce at some temperature. Alnico 5 exhibits a knee at room temperature. If the operating point of a magnet falls below the knee, small changes in H produce large changes in B, and the magnet will not be able to recover its original flux output without remagnetization.
