Abstract A radially magnetized electromagnetic sensor is proposed for the detection of the defects of the traction steel strip, which can realize the accurate detection of the defects of the traction steel strip in-situ nondestructive. Based on the electromagnetic coupling and the magnetic properties of high magnetic permeability materials, an equivalent model of the radially magnetized electromagnetic sensor is established by using the finite element analysis method. The laws of influence of the magnitude of the magnetic induction at the measurement location of the magnetized electromagnetic sensor. Finally, a radially magnetized electromagnetic sensor is prepared on the basis of numerical simulation and to measure its performance, and it is further applied to the defect detection of traction steel strips. The experimental results show that the system can realize the broken strand with a resolution of 0.5mm. This demonstrated that a feasible solution is provided for the defect detection of traction steel strips.
