The 184g weight was hung in the land recess with a string providing 0.018N force, calculated by the moment formula: the moment is force multiplied by arm, so that the required moment of 0.18N cm can be obtained. The tool accurately measures the rotation angle of the armature of the electromagnet, and meanwhile, the electromagnet fixing frame ensures that the electromagnet is locked and keeps balance.

The utility model has the beneficial effects that:

1) the electromagnet measuring tool provided by the utility model can be used for measuring the rotation angle of the armature of the electromagnet to be more than or equal to 10 degrees under the condition that the initial moment is not less than 1.8kgf cm under the detection electromagnet with the voltage of 0.18N cm, so that the performance test of the airplane speed reducing parachute bay lock electromagnet can be realized.

2) The utility model can provide different required torques by changing the size of the connecting disc or the weight of the weight so as to meet the measurement requirements of more similar products.
