Electromagnet dynamic current and dynamic resistance change rate measuring method

The invention discloses an electromagnet dynamic current and dynamic resistance change rate measurement method which comprises the following steps of: connecting circuits, connecting a power supply, and entering a detection software interface; clamping the electromagnet between the upper sliding table sliding blocks; clamping a test wire to an electromagnet binding post; adjusting the output voltage to the working voltage, and adjusting the lower sliding table to a position suitable for testing; an electromagnet iron core hits an electromagnet sensor in the mechanical part to detect data; adjusting an automatic displacement detection mode or a voltage transformation detection mode; and taking down the connected data line, and turning off the power supply. According to the invention, instantaneous dynamic current detection and dynamic resistance change rate detection generated by the coil in the action striking process of the electromagnet are realized, the measurement of the electricalparameters of the electr
