Measurement and generation of magnetic precision fields
The permanent presence of the Earth’s magnetic field turns it into an important physical parameter whose impact on aerospace activities must be taken into account. Magnetic fields play a vital role in satellite attitude control as well as in numerous scientific experiments.
Even in modern aeronautics, classic magnetic compasses are used in emergencies. They must not be affected by nearby equipment. In our unique magnetic field simulation facility (MFSA), magnetic fields are generated and measured with high precision using a tri-axial combination of 12 coils in total, with a side length of 15m.
The impact of direct and alternating magnetic fields must be taken into account during operations in heavy industrial environments. For this purpose, we use additional coil systems of various sizes to test immunity in mid-sized and small objects.
