Magnetic field simulation in embedded system with magneto-resistive sensor

Abstract

While designing embedded systems with magnetic resistance sensors, the influence of components inducted magnetic field should be estimated. The modeling of inductor, power and RS485 lines was performed using COMSOL. The modeling results allow set minimal distances between investigated components and AMR sensor. The modeling results were experimentally tested using HMC1022 sensor and data acquisition device. Ill. 12, bibl. 5, tabl. 2 (in English; abstracts in English and Lithuanian).
