Optimization of single-yoke magnetic testing by surface fields measurement

摘要

The main aim of the work is to discuss ways of optimizing a single-yoke magnetization set-up with respect to fluctuations of the measurement results due to imperfections of the yoke-sample contact. The nondestructive testing method is proposed to be optimized by simultaneous multi-point determination of surface magnetic fields of the investigated sample. The presented measurements of the surface fields are accompanied by computational modelling of the magnetic system by the finite element method.
