For the realization of the wire rope damage detection, we need to ensure uniform steady magnetic induction intensity in local wire rope.This article applies simulation soft electromagnetic analysis module and simulates several commonly used excitation test device. Analysis of electricity inside the solenoid magnetic field distribution under different structure forms. Excitation device was studied and the gas gap size, the solenoid coil section length-width ratio parameters such as size, thickness of the armature current, the induction strength of the tested steel wire rope and the influence of induction intensity distribution. There is profound guiding significance to the actual situation to select the reasonable structure of excitation test and modify the device parameters.
