Electron Paramagnetic Resonance (EPR), yotchedwanso Electron Spin Resonance (ESR) ndi njira yamagetsi yamagetsi yomwe imazindikira kusintha kwamphamvu pakati pamagetsi amagetsi osagwiritsa ntchito maginito.

Dongosolo la EPR limakhala lopangidwa ndi maginito, makina a microwave ndi makina azidziwitso zamagetsi. Makina maginito nthawi zambiri amagawika mu ma elekitiroma, maginito okhazikika ndi maginito opitilira muyeso molingana ndi mfundo yoti maginito akuluakulu amapanga maginito. Pakadali pano, maginito okhazikika ndi ma elekitiroma amagwiritsidwa ntchito kwambiri.

Maginito okhazikika amatha kukhalabe ndi mphamvu yokoka, ntchito zomanga ndi kukonza ndizotsika, ndipo zimatha kupangika kuti zikhale zotseguka komanso zazikulu m'mimba mwake, zomwe zimathandiza odwala omwe ali ndi claustrophobia.

Maginito otsegulira EPR a 0.041T opambana kwambiri opangidwa ndi CSJ ndi maginito okhazikika. Maginito okhazikika amagwiritsidwa ntchito popanga maginito okhazikika, coil yosesa imapatsidwa mphamvu kuti ipange maginito okondera, ndipo koyilo ya modulation imapatsidwa mphamvu kuti ipange maginito oyenda. Imagwira ndi zinthu zina kuti ipange pulogalamu yamagetsi yamagetsi, potero imalemba zoyeserera. Kufufuza kwa, udindo, ndi zina.
