| Abstract: | This paper introduces some magnetic parameters of magnetic material,such as magnetic hysteresis loopline, electrical resistivity and magnetore - sistivity, and the methods to measure them. From the magnetic hysteresis loopline, we can know some other parameters such as saturated magnetizing strength, magnetic conductivity, etc. Kelvin bridge has the virtues of high sensitivity, precision reading and convenience to use. It is effective tools to measure the electrical resistivity and magnetoresistivity. |
