Abstract
A two-dimensional network of alternating (N,S) magnetic poles is generated by a heavy gauge conductor (F) having an alternating current from an excitation source (G) passing therethrough. The conductor follows zigzag go and return paths (T1,T6) without any crossing, juxtaposition, or superposition, thereby simplifying construction. The invention is applicable to handling metal sheets in steel mills.
