Dongosolo la MRI ndi chida chowunikira chapamwamba kwambiri, chomwe chili ndi zofunika kwambiri pakuyika. Chizindikiro cha NMR ndi chizindikiro chofooka kwambiri, chomwe chimatha kusokoneza kunja. Chotsatira chake, machitidwe a MRI nthawi zambiri amafunika kukhala ndi zipinda za Faraday (zipinda zotetezera) kuti alekanitse kusokoneza kwa RF kunja kuti asalowe mu dongosolo. Komabe, khola la Faraday limakhala ndi kuchepetsedwa bwino kwa bandi ya ma radio frequency, ndipo chitetezo cha ma frequency otsika ndi ochepa. Makamaka pakuyika machitidwe a MRI pafupi ndi subways, masitima, ma transformer akuluakulu, ma elevator, zingwe zotumizira mphamvu, etc. Sikuti khola la Faraday liyenera kukhazikitsidwa, komanso njira yotetezera yogwira ntchito iyenera kukhazikitsidwa kuti dongosolo la MRI likwaniritse zofunikira za matenda. .

CSJ-ASH ndi otsika pafupipafupi otsika maginito amagetsi kumunda yogwira chishango dongosolo yopangidwa ndi Ningbo Chuanshan Jia Electromechanical Co., Ltd. Ikhoza kuteteza bwino DC electromagnetic minda, 50Hz/60Hz mphamvu pafupipafupi maginito minda chifukwa cha subways, masitima, tram, zingwe zotumizira, zida za thiransifoma, ma elevator, ndi zina zambiri. CSJ-ASH ili ndi zigawo zitatu zazikulu: fluxgate high-precision probe, host, ndi coil yotchinga. Chowunikira cholondola kwambiri cha fluxgate chimatha kuzindikira kusokonezedwa kwa chilengedwe cha electromagnetic field, ndikupanga chizindikiro chofananira chamagetsi kuti chiperekedwe kwa wolandirayo. Pambuyo pokonza, wolandirayo amatulutsa mphamvu yosinthira yomwe imatsatira mu nthawi yeniyeni, ndipo yapanoyo imapanga mphamvu ya maginito yosinthira mu koyilo yotchinga kuti iletse kusokoneza kwa maginito, potero kuzindikira kutchingira kokhazikika kwa minda yotsika kwambiri yamagetsi.
