| 摘要 |
The invention concerns a magnetic measurement device comprising a DC magnetic field sensor consisting of at least four discrete elongate elements, each element consisting of at least one coil and a magnetic material without remanence, said discrete elements being substantially identical; characterised in that the magnetic field sensor comprises: - a first discrete element oriented along a given axis, a second element being associated with same in order to form a first differential pair oriented along a substantially identical axis but in opposing directions, and - two other elements forming a second differential pair substantially identical to the first but oriented once more along an axis substantially identical to the axis of the first pair but in respectively opposing directions. |
