Claim:
1. A magnet assembly comprising: a plurality of coils, each of said coils being formed by multiple turns of wire embedded within monolithic structure of impregnating material formed as a cylinder with a hollow opening proceeding longitudinally therethrough, and each of said coils having a radial thickness having a mid-point; said coils in said plurality of coils being axially aligned with respect to each with the mid-point of the radial thickness of each coil being axially aligned with a part of the radial thickness of an adjacent coil; and compression blocks respectively provided between adjacent coils and configured to retain the coils in said plurality of coils in fixed relative positions with respect to each other, each compression block having opposing faces respectively in contact with adjacent coils at circumferential intervals, said compression blocks being separated by radial voids in said monolithic structure that proceed radially through said monolithic structure.
