Abstract
A non-magnetic metal for integral casting is poured into a mold supporting a couple of magnetic pole pieces with a distance piece placed therebetween. The pole pieces are thus fixed as cast integrally with the mold, and subsequently the distance piece is removed so that there are provided magnetic pole pieces of the type best suited to a nuclear magnetic resonance apparatus, etc.
