ABSTRACT:
A generally helical cut is made in a tubular conductive piece to form a winding, the winding having spaces between successive turns. The winding is axially compressed to reduce the spaces. One or more of the windings may be combined with one or more pieces of permeable or non-permeable material to form electromagnetic structures (for example, inductors or transformers) which have very high fill factors. A succession of such devices, each having possibly different numbers of turns on their windings, may be easily manufactured on a "lot-of-one" basis in an automated manufacturing environment.
