Problems solved by technology

[0002] At present, there are various regrets and deficiencies in the practical application of electromagnetic technology and magnetoelectric technology. For example, a large amount of electric energy must be consumed, and the control of the magnetic field intensity can only be realized by changing the current intensity or the number of coil turns of the electrified coil.

Embodiment Construction

[0017] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.

[0018] Since the magnetic field of a permanent magnet can exist in two forms: closed and separated, the closed magnetic field can make the permanent magnet relatively change into an ordinary substance, and does not generate any magnetic field for foreign magnets or other objects (such as iron, cobalt, nickel, etc.) Its magnetic field strength is equivalent to nothing to the outside world; while the separation magnetic field (that is, the magnetic field of the exposed magnet at the two poles in general), its magnetic field strength is very strong and obvious.

[0019] Figure 1 is a schematic diagram of the closed magnetic field properties of the present invention.

[0020] For each magnet block forming a closed magnetic field, the two extreme faces are equ...

Abstract

The invention relates to the magnetoelectric technical field, in particular to a method for utilizing low energy consumption to control the external magnetic field strength of a permanent magnet, wherein, firstly, a first closed magnetic field assembly is closely piled up together with a second closed magnetic field assembly; secondly, magnet blocks on the first closed magnetic field assembly are alternately taken off one by one to form a first isolated magnetic field assembly; thirdly, magnet blocks on the second closed magnetic field assembly are fixed together with magnetic blocks on the first isolated magnetic field assembly to form magnetic stators; fourthly, both poles of residual magnet blocks are cut to generate gaps between the poles and the magnetic stators, and the magnet blocks are integrated into a whole by fixation to form a reciprocating magnet; fifthly, the reciprocating magnet is pushed forward; when the reciprocating magnet enters into the first isolated magnetic field assembly, the prior second closed magnetic field assembly becomes the second isolated magnetic field assembly and the prior first isolated magnetic field assembly becomes the first closed magnetic field assembly, thereby realizing the control to the external magnetic field strength of the permanent magnet by variation of positions of the reciprocating magnet.

Description

Technical field: [0001] The invention relates to the field of magnetoelectric technology, in particular to a method for controlling the intensity of the external magnetic field outside a permanent magnet by using low energy consumption. Background technique: [0002] At present, there are various regrets and deficiencies in the practical application of electromagnetic technology and magnetoelectric technology. For example, a large amount of electric energy must be consumed, and the control of the magnetic field strength can only be realized by changing the current intensity or the number of turns of the electrified coil. Modern society advocates the promotion of environmental resource protection, sustainable development, energy saving, consumption reduction and emission reduction. Therefore, it has become very important to fully develop and utilize the hidden potential and latent potential of magnetic resources. Invention content: [0003] The invention provides a method ...
