A permanent magnet structure comprising multiple hollow substantially cylindrical flux sources embedded one within another about an axially extending center passage such that each flux source is free to rotate in either direction by any desired angular magnitude independent of the motion of the other(s). In the case of a plurality of axially aligned truncated HCFS structures, the array may be arranged to provide a periodic magnetic struture suitable for use in a wiggler, or with a helical locus suitable for use in a twister.

A magnetic structure comprising a plurality of hollow substantially cylindrical flux sources embedded one within another about an axially extending central cavity, the outer radius of one flux source being substantially equal to the inner radius of the next surrounding flux source, each flux source being free to independently rotate about the axis in either direction and by any angular amount, said plurality of flux sources serving to produce a uniform high field in said central cavity.
