I-magnetic loop inductor licandelo lombane. Umsebenzi wayo ophambili kukuguqulwa kwe-electromagnetic induction. Intambo yombane yeyona inductance ilula. Isetyenziswa njenge-eriyali ukuguqula amandla ombane abe ngamaza ombane. Ikhoyili ye-air-core inzima ngakumbi kune-eriyali. , Isetyenziselwa ukukhetha i-loop kunye ne-RF yokuhambisa isekethe;
Iikhoyili zomoya zidla ngokuba ne-inductance ephantsi kakhulu kwaye azinazibhexeshi zemagnethi. Ukongeza kwii-antenna kunye nee-coil-core coil, kukho kwakhona i-inductors e-I-shaped, engasetyenziselwa ukucoca kunye nokugcinwa kwamandla. Kukwakho ii-inductors zemowudi ye-magnetic ring eziqhelekileyo ezinokusetyenziswa ukucinezela uphazamiseko.

Izinto ezikwibhodi yePC, ezinje nge resistors, capacitors, kunye nee chips, zombini zizinto zokuphazamiseka kombane kunye nomthombo wokuphazamiseka kombane ngexesha lokusebenza. Uphazamiseko lwe-electromagnetic lunokwahlulwa ngokweendidi ezimbini: uphazamiseko lwemowudi eyahlukileyo (uphazamiseko lwemowudi yothotho) kunye nophazamiseko lwemowudi eqhelekileyo (ukuphazamiseka komhlaba).
Thatha iingcingo ezimbini ze-PCB kwi-motherboard (iingcingo ezidibanisa amacandelo e-motherboard) njengomzekelo. Into ebizwa ngokuba yi-different mode interference ibhekisela kukuphazamiseka phakathi kweengcingo ezimbini; uphazamiseko lwemowudi eqhelekileyo luphazamiseko phakathi kweengcingo ezimbini kunye nePCB yomhlaba. Ukuphazamiseka okubangelwa ngumahluko onokwenzeka. Uphazamiso lwemowudi yomahluko isebenza ngoku phakathi kwemigca yomqondiso emibini,
Umkhombandlela wayo wokuqhuba uhambelana ne-waveform kunye nesignali yangoku; imowudi yokuphazamiseka yangoku isebenza phakathi komgca wesignali kunye nocingo oluphantsi, kwaye i-interference current ihamba ngesiqingatha seengcingo ezimbini zesignali kwicala elifanayo, kwaye ucingo lomhlaba luyi-loop eqhelekileyo.

Ekubeni ukusetyenziswa kwe-anti-interference magnetic ring kwisekethe kunokunyusa ilahleko ye-high-frequency ngaphandle kokwazisa ilahleko ye-DC, isiphumo sokucinezela imiqondiso yengxolo ngaphezu kwe-frequency ephezulu ibonakala kakhulu, ngoko ke i-magnetic ring inductance isetyenziswa ngokubanzi kwiibhodi ze-PCB zesekethe.
Undoqo we-magnetic inductor i-brittle kwaye kulula ukuba yonakaliswe xa iwisiwe. Ngoko ke, amanyathelo okukhusela kufuneka athathwe ngexesha lokuthutha. Xa uyila, amandla afunwa yisekethe kufuneka ahambelane ne-toroidal inductance yamagnetic. Ukuba amandla makhulu kakhulu, i-inductance iya kufudumeza ukuya kwiringi kazibuthe Emva kobushushu beCurie
