More Information
Summary:The invention relates to a magnetic amplification device comprising a magnetic sensor with longitudinal sensitivity, having a first piece of magnetic material and a second piece of magnetic material, each of the pieces having a longitudinal slot at its center, the pieces being separated by a distance called the gap, and the magnetic sensor being inserted into the two slots. The device of the invention typically makes it possible to measure low magnetic fields smaller than the Earth's field using a magnetic sensor of the AMR type.
