Iyo magnetic loop inductor chinhu chemagetsi.Basa rayo guru kutendeuka kwe electromagnetic induction.Waya yemagetsi ndiyo yakareruka inductance.Inoshandiswa senge antenna kushandura simba remagetsi kuita electromagnetic waves.Iyo mhepo-yepakati coil yakanyanya kuoma kupfuura iyo antenna., Inoshandiswa kune frequency kusarudzwa loop uye RF transmitting circuit;
Air-core coils kazhinji ane yakaderera inductance uye haana magineti conductor.Mukuwedzera kune antennas uye air-core coils, kune zvakare I-shaped inductors, iyo inogona kushandiswa kusefa uye kuchengetedza simba.Kune zvakare magineti mhete common mode inductors inogona kushandiswa kudzvanyirira kupindira.

Izvo zvikamu zviri paPC board, senge resistors, capacitors, uye machipisi, ese ari emagetsi kupindira chinhu uye sosi yekukanganisa kwemagetsi panguva yekushanda.Kupindira kweElectromagnetic kunogona kukamurwa kuita zvikamu zviviri: mutsauko modhi kupindira (yakatevedzana modhi kupindira) uye yakajairika modhi kupindira (pasi kupindira).
Tora waya mbiri dzePCB pabhodhi reamai (waya dzinobatanidza zvikamu zvebhodhi reamai) semuenzaniso.Iyo inonzi differential mode interference inoreva kukanganisa pakati pewaya mbiri;the common mode interference ndiko kukanganisa pakati petambo mbiri nePCB ground wire.Kupindira kunokonzerwa nekugona kusiyana.Differential mode kupindira ikozvino zviito pakati pemitsara miviri yechiratidzo,
Kutungamira kwayo kunoenderana neiyo waveform uye chiratidzo chazvino;the common mode interference current acts between the signal line and the ground wire, and the interference current inoyerera nepakati pehafu yewaya mbiri dzechiratidzo munzira imwe chete, uye wire yepasi ndiyo yakajairika loop.

Sezvo kushandiswa kwe-anti-interference magineti mhete mudunhu kunogona kuwedzera-yakawanda-frequency kurasikirwa pasina kuunza DC kurasikirwa, mhedzisiro yekudzvanya masaini eruzha pamusoro pepamusoro frequency iri pachena, saka magineti mhete inductance inoshandiswa zvakanyanya pamatunhu PCB mabhodhi.
Iyo yakakosha yemagnetic toroidal inductor ine brittle uye iri nyore kukuvara kana yadonha.Nokudaro, matanho ekudzivirira anofanira kutorwa panguva yekufambisa.Paunenge uchigadzira, simba rinodiwa nedunhu rinofanira kufanana nemagnetic toroidal inductance.Kana simba racho rakanyanya kukura, inductance ichapisa kusvika kune magnetic ring Mushure mekushisa kweCurie
