The structure of the magnetic excitation circuit can significantly impact the Magnetic Flux Leakage (MFL) signal of rail inspection. This research proposes a unique approach for analyzing the influence of steel brushes in MFL detection equipment based on finite element simulation results. The magnetic circuit equation is established to investigate the magnetic resistance. Next, the MFL detection with steel brushes of different thicknesses and without steel brushes is compared and analyzed in the finite simulation model. The finite element situation results show that the MFL signal does not change linearly as the parameters are changed. This method demonstrates that the structure of the detection equipment with steel brush can generate the MFL signals with a higher signal-to-noise ratio.
