Measurement system for magnetic field sensors testing with earth’s magnetic field compensation

Abstract

The design and construction of a measurement system for magnetic field sensors testing with a maximum induction range of 10 mT was described. In order to verify the uniformity of the magnetic field, the distribution of the field in the measurement area was measured. Main goals of the construction were: the ability to compensate for the Earth’s magnetic field and high uniformity of the generated field in the working area of the system. Therefore, a coil arrangement similar to the Helmholtz coils was used. The study also includes the design of the software realized in LabView environment.
