Demagnetization value of various shapes
WebFeb 28, 2024 · Fig. 2: Hysteresis loop. The value of flux density (i.e. B r) when exciting current and therefore magnetic field strength is reduced to zero is called remanent or residual flux density and is taken as a measure of the residual magnetism. After this, let us demagnetize the test piece. For this, we will have to pass the current through the coil in … WebA demagnetization curve describes the magnetic qualities of a magnet more completely than a single number like Pull Force or Surface Field. It provides information about the strength of the magnet, how hard it is to demagnetize, and how a magnet's shape (or use in a magnetic circuit) affects matters.
