ʻO ka Electron Paramagnetic Resonance (EPR), i kapa ʻia ʻo Electron Spin Resonance (ESR) kahi ʻenehana resonance magnetic e ʻike i ka hoʻololi ʻana o ka resonance ma waena o nā mokuʻāina o nā electrons i hoʻopaʻa ʻole ʻia i loko o kahi māla magnetic i noi ʻia.

ʻO ka ʻōnaehana EPR ka mea maʻamau i kahi ʻōnaehana magnet, kahi ʻōnaehana microwave a me kahi ʻōnaehana ʻike uila. Hoʻokaʻawale ʻia ka ʻōnaehana magnet i nā electromagnets, nā magnet mau loa a me nā superconducting magnets e like me ke kumumanaʻo e hoʻohua ai ka māla magnetic nui i ka māla magnetic. I kēia manawa, hoʻohana mau ʻia nā magnet mau a me nā electromagnets.

Hiki i nā magnet paʻa ke mālama mau i ka magnetism, ʻoi aku ka haʻahaʻa o kā lākou kūkulu ʻana a me ka mālama ʻana, a hiki ke hoʻolālā ʻia e wehe a nui ke anawaena, ʻo ia ka pōmaikaʻi no nā maʻi me ka claustrophobia.

ʻO ka 0.041T super nui wehe EPR magnet i hana ʻia e CSJ he magnet mau loa. Hoʻohana ʻia nā magnet paʻa no ka hoʻoulu ʻana i kahi kahua magnetic static, hoʻoikaika ʻia ka sweep coil e hoʻohua i kahi māla magnetic bias, a hoʻoikaika ʻia ka coil modulation e hoʻohua i kahi māla magnetic modulated. Hana ia me nā ʻāpana ʻē aʻe e hana i kahi hōʻailona resonance paramagnetic uila, a laila e haku i ka laʻana hoʻāʻo. Ka nānā 'ana o, kūlana, etc.
