Electron Paramagnetic Resonance (EPR), yomwe imatchedwanso Electron Spin Resonance (ESR) ndi njira ya maginito yomwe imazindikira kusintha kwamphamvu pakati pa mphamvu ya ma elekitironi osayanjanitsidwa mumlengalenga wogwiritsidwa ntchito.

Dongosolo la EPR nthawi zambiri limapangidwa ndi maginito, makina a microwave ndi makina ozindikira zamagetsi. Dongosolo la maginito nthawi zambiri limagawika ma elekitiromagineti, maginito osatha ndi maginito a superconducting malinga ndi mfundo yakuti gawo lalikulu la maginito limapanga mphamvu ya maginito. Pakadali pano, maginito okhazikika ndi ma electromagnets amagwiritsidwa ntchito kwambiri.

Maginito osatha amatha kusunga maginito kwamuyaya, ndalama zawo zomanga ndi kukonza ndizochepa, ndipo zimatha kupangidwa kuti zikhale zotseguka komanso zazikulu m'mimba mwake, zomwe zimathandiza odwala omwe ali ndi claustrophobia.

Maginito a 0.041T otsegula kwambiri a EPR opangidwa ndi CSJ ndi maginito osatha. Maginito osatha amagwiritsidwa ntchito kuti apange malo okhazikika a maginito, kusesa koyilo kumapatsidwa mphamvu kuti apange mphamvu ya maginito yokondera, ndipo koyilo yosinthira imapatsidwa mphamvu kuti ipange mphamvu ya maginito. Zimagwira ntchito ndi zigawo zina kuti zipange chizindikiro chamagetsi cha paramagnetic resonance, ndikupanga zitsanzo zoyesa. Kusanthula, udindo, ndi zina.
