More Information
Summary:The utility model provides a magnetic parameter measuring device for a magnetic material. The measuring device comprises a winding which is wound around the magnetic material to be measured, a voltage regulation circuit for changing the voltage across the two ends of the winding, an integrator enabling the phase of output voltage to be the same with that of input current of the winding via phase shift, a dual trace oscilloscope for reading the transient current of the winding and the output voltage of the integrator and observing a hysteresis curve, a sampling resistor for sampling current, an ammeter for monitoring the value of current flowing through the winding, and a voltmeter for monitoring the output voltage of the integrator. The magnetic parameter measuring device for the magnetic material is simple in structure, low in cost and controllable in measuring precision.
