Electron Paramagnetic Resonance (EPR), e taʻua foi o le Electron Spin Resonance (ESR) o se metotia resonance maneta lea e maitauina le resonance fesuiaiga i le va o malosiaga setete o le faʻaaluina electron i se faaaogaina maneta fanua.

O le EPR system e masani ona aofia ai le magnet system, o le microwave system ma le electronic detection system. O le maneta faiga e masani ona vaevaeina i electromagnets, tumau maneta ma superconducting maneta e tusa ai ma le mataupu faavae o le autu maneta fanua fausiaina le maneta fanua. I le taimi nei, o magnets tumau ma electromagnets e masani ona faʻaaogaina.

Maneta tumau mafai tumau tumau magnetism, latou fausiaina ma tausiga tau e fai si maualalo, ma e mafai ona latou fuafuaina e tatala ma tele i le lautele, o se manuia mo tagata mamaʻi ma claustrophobia.

O le 0.041T maoae tele tatalaina EPR maneta gaosia e CSJ o se tumau maneta. Magnets tumau o loʻo faʻaaogaina e fausia ai se faʻamautuina static maneta fanua, o le saluina coil o loʻo faʻamalosia e faatupuina ai se bias maneta mala, ma le modulation coil e faʻamalosia e fausia ai se modulated malae maneta. E galue ma isi vaega e gaosia ai se eletise paramagnetic resonance faʻailo, ma tusia ai le faʻataʻitaʻiga faʻataʻitaʻiga. Iloiloina o, tulaga, ma isi
