Magnetic Hysteresis Cycle Measurements With a New Needle Probe Setup

Year: 2024

Type: article

Abstract: Different magnetic needle probe setups are presented, and their strengths and weaknesses are investigated. A new configuration, combining the advantages of the other setups, is presented. Finite element (FE) simulations are implemented to explore the effect of the excitation yokes and residual stresses on the magnetic flux symmetry. The error sources affecting the accuracy of the experimental measurements are analyzed and quantified. Solutions to minimize these errors are also proposed. By minimizing error sources, the obtained experimental measurements closely follow the reference hysteresis loop obtained from a wrapping coil in the unidirectional case. The proposed measurement device notably provides enhanced accuracy for surface measurements when wrapping coils are not implementable.
