Abstract
A process permits the determination of multi-dimensional distribution of magnetic fields. The process uses a magneto-resistive sensor as a physical measuring device. The measuring device is coupled with a method for algebraic reconstruction so that sectional images of the field distribution are calculated from individual measurements of the magneto-resistive effect using the algebraic reconstruction.
