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 ene-I-shaped, engasetyenziselwa ukucoca kunye nokugcinwa kwamandla.Kukwakho ne-magnetic ring common inductors 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 lunokwahlulahlulwa ngokweendidi ezimbini: uphazamiseko lwemowudi eyahlukileyo (ukuphazamiseka kwemowudi yothotho) kunye nokuphazamiseka kwemowudi 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
