Electron Paramagnetic Resonance (EPR), wanda kuma ake kira Resonance Electron Spin Resonance (ESR) wata dabara ce ta maganadisun magnetic wanda ke gano jujjuyawar resonance tsakanin jihohin kuzari na na'urorin lantarki da ba a gyara su ba a cikin filin magnetic mai amfani.

Gabaɗaya tsarin EPR ya ƙunshi tsarin magnet, tsarin microwave da tsarin gano lantarki. Gabaɗaya tsarin magnet ɗin ya kasu zuwa electromagnets, magnet na dindindin da manyan abubuwan haɓakawa bisa ƙa'idar cewa babban filin magnetic yana haifar da filin magnetic. A halin yanzu, ana amfani da maganadisu na dindindin da electromagnets.

Magnet na dindindin na iya kula da maganadisu na dindindin, farashin ginin su da na kulawa ba su da ƙima, kuma ana iya tsara su don buɗewa da manyan diamita, wanda shine fa'ida ga marasa lafiya da claustrophobia.

Babban girma 0.041T babban maganadisu na EPR wanda CSJ ya samar shine maganadisu na dindindin. Ana amfani da madafan iko na dindindin don samar da madaidaiciyar madaidaiciyar filin magnetic, murfin murƙushewa yana da ƙarfi don samar da filin magnetic na son zuciya, kuma murƙurin juzu'in yana da ƙarfi don samar da madaidaicin filin magnetic. Yana aiki tare da wasu abubuwan don samar da siginar siginar siginar lantarki, don haka ya haɗa samfurin gwajin. Nazarin, matsayi, da sauransu.
