ABSTRACT:
A magnetic field measuring head comprises the following elements integrated into one and the same substrate: a light source, a light guide insensitive to the magnetic field, a layer of magnetic material which, when plunged into a magnetic field to be measured, causes the rotation of the plane of polarization of the light coming from the source, and a device to measure the rotation of the plane of polarization of the light.
