Apparatus and method for measuring magnetic fields |
摘要 |
An apparatus for measuring a magnetic field is described, which comprises a core and an exciter coil for remagnetizing the core material. The remagnetizable core material is embodied as a layer or as multiple layers disposed at a distance from one another, and the core has a maximum total extension G where 2.5 mm≧G≧0.2 mm, a ratio of length to width that is greater than or equal to a value of twenty, and a thickness D where 2 μm≧D≧0.2 μm. Also described is a corresponding method for measuring a magnetic field. |

1. An apparatus for measuring a magnetic field, comprising:
a core including a remagnetizable core material and an exciter coil for remagnetizing the remagnetizable core material, wherein:
the remagnetizable core material includes multiple layers of the remagnetizable core material disposed at a distance from one another;a ratio of length to width of the core is greater than or equal to a value of twenty;a thickness of the core is D;2 μm≧D≧0.2 μm;a thickness of each individual one of the layers is DS; and60 nm≧DS≧20 nm. |
