B8.1 - Accurate Measurement Setup for Strongly Inhomogeneous Magnetic Fields

H. Husstedt, M. Kaltenbacher & U. Ausserlechner
The testing of magnetic sensors for automotive applications includes not only electrical but also magnetic tests. For each sensor, dedicated test equipment generates magnetic reference fields which vary from homogeneous, to differential and rotating fields. Some of these fields are strongly inhomogeneous with a gradient up to 1%/10μm. For the analysis of these test equipments, the spatial dependency of the reference fields has to be measured around the position where the sample is placed during...
