| Abstract: | If one knows the diagram of demagnetization of the magnet in plastic binder and knows the packing density, the curve of demagnetization of the used magnetic powder can be plotted. This procedure may also be inverted. Using anisotropic magnets with binders, a technical sufficient orientation must be required for calculating the curve of demagnetization. By comparing calculated and measured values, defects of the base materials, grindet powder, granulate, molding process, or magnetic orientation may be become known and removed. |
