ʻO ka inductor loop magnetic kahi mea uila.ʻO kāna hana nui ka hoʻololi ʻana o ka induction electromagnetic.ʻO ka uea uila ka inductance maʻalahi.Hoʻohana ʻia ia ma ke ʻano he antenna e hoʻololi i ka ikehu uila i nā hawewe electromagnetic.ʻOi aku ka paʻakikī o ka coil air-core ma mua o ka antenna., Hoʻohana ʻia no ka loop koho alapine a me ka RF transmitting circuit;
He haʻahaʻa loa ka inductance o ka ea-core coils a ʻaʻohe conductors magnetic.Ma waho aʻe o nā antennas a me nā coils air-core, aia kekahi mau inductors I-shaped, hiki ke hoʻohana ʻia no ka kānana a me ka mālama ʻana i ka ikehu.Aia kekahi mau mea hoʻokomo maʻamau maʻamau i hiki ke hoʻohana ʻia e hoʻopaʻa i ka interference.

ʻO nā ʻāpana ma ka papa PC, e like me nā resistors, capacitors, a me nā chips, he mea hoʻopilikia electromagnetic a me kahi kumu o ka interference electromagnetic i ka wā o ka hana.Hiki ke hoʻokaʻawale ʻia ka hoʻopili electromagnetic i ʻelua mau ʻāpana: ʻokoʻa ke ʻano o ke ʻano (series mode interference) a me ke ʻano maʻamau (interference ground).
E lawe i nā uea PCB ʻelua ma ka motherboard (nā uea e hoʻopili ana i nā ʻāpana o ka motherboard) ma ke ʻano he laʻana.ʻO ka mea i kapa ʻia ke ʻano ʻokoʻa ʻokoʻa e pili ana i ka interference ma waena o nā uea ʻelua;ʻO ke ala maʻamau ka hoʻopili ʻana ma waena o nā uea ʻelua a me ka uea honua PCB.Hoʻopilikia ʻia e ka ʻokoʻa hiki.Hana ʻia ke ʻano ʻokoʻa ma waena o nā laina hōʻailona ʻelua,
ʻO kona kuhikuhi conduction e kūlike me ka nalu a me ka hōʻailona o kēia manawa;ʻO ke ʻano hoʻohālikelike maʻamau e hana nei ma waena o ka laina hōʻailona a me ka uea honua, a ke kahe nei ke au i ka hapalua o nā uea hōʻailona ʻelua ma ka ʻaoʻao hoʻokahi, a ʻo ka uea honua ka loop loop.

Ma muli o ka hoʻohana ʻana i ke apo magnetic anti-interference i ke kaapuni hiki ke hoʻonui i ka nalo kiʻekiʻe me ka ʻole o ka hoʻokomo ʻana i ka nalowale DC, ʻike maopopo loa ka hopena o ke kāohi ʻana i nā hōʻailona walaʻau ma luna o ke alapine kiʻekiʻe, no laila ua hoʻohana nui ʻia ka inductance ring magnetic ma nā papa PCB circuit.
ʻO ke kumu o ka magnetic toroidal inductor he palupalu a maʻalahi ke hōʻino ʻia ke hāʻule.No laila, pono e mālama ʻia nā hana palekana i ka wā o ka lawe ʻana.I ka hoʻolālā ʻana, pono ka mana e koi ʻia e ke kaapuni i ka magnetic toroidal inductance.Inā nui ka mana, e wela ka inductance i ke apo magnetic Ma hope o ka mahana Curie
