Abstract
A magnetic field measuring device having a cantilevered, mechanically vibratable, rectangular substrate strip, at least one flat side of the substrate strip being coated with a magnetostrictive material system, further having drive means designed for the temporally periodic exertion of a force component directed perpendicular to the flat sides of the substrate strip on at least one part of a flat side of the substrate strip with a predetermined excitation frequency and having a detection device for detecting an electrical signal generated by the vibration of the substrate strip, wherein a. the substrate strip is formed from a material with a modulus of elasticity greater than 5 GPa and b. the excitation frequency is set up as a function of the dimensions of the substrate strip in such a way that the substrate strip oscillates in mechanical resonance and forms a U-mode, and c. the detection device has an induction coil which surrounds the substrate strip in a contactless manner and has a coil axis aligned along the substrate strip.
