Abstract

Et magnetarrangement for å generere et NMR-kompatibelt, monogent permanentmagnetfelt presenteres. Oppfinnelsen er kjennetegnet ved at to permanente magneter, heretter kalt hovedmagneter, er tilveiebrakt, som hver har et magnetpolflateareal, der magnetpolflatearealene er anordnet parallelt og i avstand fra hverandre slik at hovedmagnetene avgrenser et mellomrom på begge sider gjennom sine magnetflatearealer, hvor magnetpolflatene til hovedmagnetene hver har en magnetisk polarisering motsatt av hverandre, i det minste to ringformede permanentmagneter er anordnet, i det følgende referert til som ringmagneter, som er plassert koaksialt med hverandre og som i fellesskap radialt avgrenser et indre ringkammer, og ringmagnetene er plassert i forhold til de to hovedmagnetene på en slik måte at det indre ringkammeret i det minste regionalt omslutter mellomrommet, og magnetfeltene til hovedmagnetene og ringmagnetene er konstruktivt overlagret.
