Abstract

The invention belongs to the technical field of magnetic field intensity measuring devices, and particularly relates to a magnetic field intensity measuring device. The device comprises a cylindrical container, and a light source is arranged at one end in the cylindrical container. Non-deformable materials are mounted at the ends, close to the light source, of the top and the bottom of the cylindrical container through connecting arms. Giant magnetostrictive material rods are arranged on the sides, close to the cylindrical container, of the non-deformable materials, and giant magnetostrictive material connecting parts are arranged on the non-deformable materials. Fulcrums are arranged at the end, close to the connecting arm, of the top of the cylindrical container and the end, close to the connecting arm, of the bottom of the cylindrical container, and light levers are arranged at the ends, away from the cylindrical container, of the fulcrums. A light detector is arranged at the end, away from the light source, of the cylindrical container. The magnetic field causes the deformation of the giant magnetostrictive material to drive the light levers to stretch a graphene film, so that the space between the noble metal particles is changed, finally, the transmitted light is changed, the magnetic field intensity is obtained according to the change relation, and the device has the advantages of high sensitivity and high precision.

Description

technical field [0001] The invention relates to the technical field of magnetic field strength measuring devices, in particular to a magnetic field strength measuring device.
