Magnetic stray field analysis over large areas using Hall- and magneto-optical sensors

Benjamin Wenzel, Matthias Schmidt

Abstract

In this paper, fast and large-area measurements using Hall sensors and magneto-optical sensors are presented, which are suitable for 100% inline testing of magnetic assemblies in industry. The advantages of the two methods are explained and illustrated using real measurement examples. We show how identically designed magnetic components can be compared easily and quickly based on their stray fields. High-resolution measurements of miniaturized magnetic structures are carried out using magnetooptical measurement technology and the results are presented.
