Method and device for measuring static magnetic force

Abstract

The invention discloses a method and a device for measuring static magnetic force. The method comprises the following steps: blocking pieces with different thicknesses are arranged between the permanent magnet and the magnetic conductive column; the deflector rod is poked to lower the position of the spring balance, the reading is smaller than 0, then the deflector rod slightly rotates the screw to lift the spring balance, the reading of the spring balance reaches the maximum value, and at the moment, the reading of the spring balance is the thickness of the blocking piece with the corresponding thickness, namely the static magnetic force of the air gap between the permanent magnet and the magnetizer. The device comprises a supporting system, a tension measuring system, a static magnetic field fixing system and the like. The static magnetic field fixing system is composed of two static magnetic field supporting blocks and two pressing blocks, and the pressing blocks fix the reflector containing the permanent magnet to the static magnetic field supporting blocks. The invention provides a method and a device for measuring the static magnetic force, an example static magnetic mechanical model is provided through measurement, and the method and the device are applied to measurement of the static magnetic force between a permanent magnet and a soft magnetic material and can also beapplied to occasions such as tensile stress measurement and the like.

Description

technical field [0001] The present invention relates to the technical field of magnetostatic force measurement, in particular to a method and device for measuring static magnetostatic force. Background technique [0002] In terms of performance and use, magnetic materials can be divided into two categories: soft magnetic materials and hard magnetic materials according to the size of the coercive force. Soft magnetic materials are called soft magnetic materials with small coercive force, and hard magnetic materials with large coercive force. Soft magnetic materials are suitable for alternating magnetic fields. For example, the iron cores of inductance components, transformers, motors, generators, etc. are all soft magnetic materials. maded. The hard magnetic material can also become a permanent magnet, which can retain a strong residual magnetization after the external magnetic field is withdrawn, and can generate a stable magnetic field. The systems driven by electromagnet...
