Summary: | The utility model discloses a soft-magnetic-material-magnetic-conductivity measurement experiment device based on an oscilloscope and a signal generator. The device includes a sample frame, an excitation coil, an induction coil, the signal generator, a sampling resistor and the oscilloscope, wherein an annular to-be-tested soft-magnetic material is arranged on the sample frame; circled excitation and induction coils are wound on the annular to-be-tested soft-magnetic material; the signal generator is serially connected with the excitation coil so as to form an excitation circuit; the sampling resistor is serially connected with the excitation circuit; and a measurement end A of the oscilloscope is connected with the two ends of the sampling resistor and a measurement end B of the oscilloscope is connected with the two ends of the induction coil and thus an induction circuit is formed. Therefore, magnetic conductivity of the to-be-tested soft-magnetic material can be obtained through Ampere circuital theorem a |
