Abstract
The invention relates to an improved micro-fluxgate magnetometer capable of reducing noise phenomena that can occur when measuring a magnetic field, in a simple manner, and a method for manufacturing such a magnetometer in thin layers.
Claims10
Micro-fluxgate magnetometer comprising:
- an open magnetic circuit comprising at least one magnetic core based on a magnetic material with at least two free ends,
- one or several detection windings wound around the core,
- one or several excitation windings wound around the magnetic core, so as to enable the entire magnetic material to reach saturation.
