Abstract

The invention discloses a multifunctional soft magnetic material measuring device which comprises an instrument main frame with a hollow channel, and an instrument main panel arranged on the instrument main frame, wherein, a through hole corresponding to the hollow channel of the instrument main frame is formed in the middle of the instrument main panel; the through hole passing through the instrument main panel is inserted into a central device in the hollow channel of the instrument main frame; a measured sample is positioned in the central device; and the instrument main panel is used for fixing the central device and the measured sample in the central device. The invention has the advantages of simple structure, convenient operation, fast measurement and exact results, and realizes the measurement to the four magnetic parameters (i.e. the initial permeability, the saturation magnetic induction, the magnetic anisotropy constant and the magnetostriction constant) of the same zonal soft magnetic material by using one instrument.

Description

technical field [0001] The present invention relates to one. In particular, it relates to a multifunctional soft magnetic material measuring device which can realize the measurement of four magnetic parameters of the same strip-shaped soft magnetic material sample by using one measuring instrument. Background technique [0002] In order to adapt to the development of nanocrystalline alloy materials, the relevant magnetic measurement equipment should also be continuously updated. The main magnetic indicators for amorphous and nanocrystalline soft magnetic materials include: magnetization, permeability, magnetic anisotropy, and magnetostriction. In order to make a comprehensive evaluation of the soft magnetic properties of this material, simultaneous measurements of the initial permeability, saturation magnetic induction, magnetic anisotropy constant, and magnetostriction coefficient are required. At present, indirect measurement of inductance is generally used to measure in...
