Abstract
A device is disclosed for measuring low-flux magnetic fields with a sensor operating according to the core saturation principle. The sensor is provided with a ferromagnetic core, an excitation coil and a measuring coil. The measuring coil, the excitation coil and the ferromagnetic core are electrically insulated from one another, each being disposed in a single, separate, parallel layer on a support material.
