Abstract

The invention discloses a magnetic field adjuster which is capable of adjusting external magnetic fields. The adjuster comprises K-level super-conduction coils, a super-conduction switch, a first electronic element, at least one second electronic unit, a position adjuster and a biasing circuit, wherein K is a positive integer larger than 1. The K-level super-conduction coils are arranged in an internal and external mode, the super-conduction coils of different levels in the K-level super-conduction coils are connected in series to form closed coils, the K-level super-conduction coils are connected in series with the first electronic element, and one second electronic unit is welded between each winding turn of at least one winding turn of the at least one super-conduction coils. The position adjuster is used for adjusting the relative positions between different levels of super-conduction coils of the K-level super-conduction coils. The biasing circuit comprises a biasing coil and a biasing power supply to be used for generating a direct-current magnetic field, and the super-conduction switch is arranged on the closed coils to be used for adjusting the operation state of the K-level super-conduction coils.

Description

technical field [0001] The invention relates to the field of electromagnetic compatibility, in particular to a magnetic field regulator. Background technique [0002] With the continuous development of human civilization, the electromagnetic environment is deteriorating day by day. Electromagnetic noise is especially serious around high-voltage lines, large electrical appliances, and large steel structures. Magnetic field cancellation is a common support technology for many precision sciences. In some extreme measurement environments: such as high-precision atomic clock electron beam imaging devices, mass spectrometers, medium and micro Widely referenced in subprobing. In some biomagnetic measurements, the signals to be measured are mostly in the order of 10pT (1×10-11) or even lower. The ambient noise magnetic field is 3-6 orders of magnitude larger. Removing noisy signals becomes an essential part of this type of measurement. [0003] There are two commonly used magnet...
