Устройство позволяет экранировать магнитное поле в необходимом объеме пространства путем индуцирования магнитного поля необходимой мощности компенсирующими обмотками при минимальном влиянии на экранируемый источник магнитного поля. Датчик магнитного поля измеряет мощность поля, полученный сигнал поступает на управляемый усилитель, к выходу которого подключены компенсирующие катушки-обмотки, которые индуцируют магнитное поле, противоположное измеренному. В результате напряженность магнит-поля уменьшается, при этом связь магнитного поля обмоток и источника минимальна.The device allows shielding the magnetic field in the required volume of space by inducing a magnetic field of the required power with compensating windings with minimal effect on the shielded source of the magnetic field. A magnetic field sensor measures the power of the field, the received signal is fed to a controlled amplifier, to the output of which compensating winding coils are connected, which induce a magnetic field opposite to that measured. As a result, the magnet-field strength decreases, while the coupling between the magnetic field of the windings and the source is minimal.
