I-Electron Paramagnetic Resonance (EPR), ekwabizwa ngokuba yi-Electron Spin Resonance (ESR) bubuchule beresonance yemagnethi echonga ukuguquka kweresonance phakathi kwamandla ee-electron ezingasebenziyo kumhlaba osetyenziswayo wemagnethi.

Inkqubo ye-EPR ngokuqhelekileyo yenziwe yinkqubo yemagnethi, inkqubo ye-microwave kunye nenkqubo yokubona i-electronic. Inkqubo yemagnethi yahlulahlulwe ngokubanzi ibe ziimagnethi, iimagnethi ezisisigxina kunye neemagnethi ezinkulu ngokomgaqo wokuba eyona ndawo iphambili kazibuthe ivelisa umhlaba. Okwangoku, iimagnethi ezisisigxina kunye ne-electromagnets zisetyenziswa ngokuqhelekileyo.

Iimagnethi ezisisigxina zinokugcina imagnethi ngokusisigxina, iindleko zabo zokwakha kunye nokugcinwa kwazo ziphantsi, kwaye zinokuthi ziyilwe ukuba zivuleke kwaye zibe zikhulu ngobubanzi, nto leyo eluncedo kwizigulana ezine-claustrophobia.

I-0.041T enkulu yokuvula imagnethi ye-EPR eveliswe yi-CSJ yimagnethi esisigxina. Iimagnethi ezisisigxina zisetyenziselwa ukuvelisa umhlaba ozinzileyo wemagnethi, i-coil yokutshayela inamandla okuvelisa intsimi yemagnethi ecalanye, kwaye ikhoyili yokumodareyitha inikwe amandla ukuvelisa intsimi yemagnethi emodareyithiweyo. Isebenza namanye amacandelo ukuvelisa i-electronic paramagnetic resonance signal, ngaloo ndlela iqulunqa isampulu yovavanyo. Uhlalutyo, ubume, njl.
