In this case, the width of the closed circuit, which is plural in the direction perpendicular to the movement direction of the square or hexagon, should be less than 1/3 of the interval between the magnetic poles so as not to cancel the rotational force and the electromotive force at the boundary of the magnetic poles.

Cylindrical thin-film coils of three-phase half-wave and radio waves are formed by repeatedly forming rectangular or hexagon thin-film coils having a plurality of circuits on upper and lower copper foils with a long insulating film therebetween at intervals of magnetic poles, and connecting thin-film coils formed above and below in series.
