Abstract

PURPOSE: To reduce an electromagnetic force which acts to a conductor, to simplify a conductor support, to utilize a conductor of low ridigity and to provide an economic conductor device, by changing the disposition dimensions of pairs of conductors such as lead wires.

CONSTITUTION: Currents are caused to flow forward and backward through a pair of conductors 31, 32 and another pair of conductors 33, 34. The distance A between the conductors 31, 32 and between the conductors 33, 34 is set larger than that between the conductors 32, 33. A force, which acts between two conductors of W in width at a distance of A when a forward and a backward currents flow through the conductors, is shown by a formula on the simplifying assumption that the currents concentrate to the center of the thickness of the conductors and are uniformly distributed along their width. In the formula, F denotes the electromagnetic force per unit length of the conductors and I denotes a current per conductor. An electromagnetic force complying with the formula is applied to the conductor 31 leftward from the conductor 32, rightward from the conductor 33 and leftward from the conductor 34. This results in reducing the electromagnetic forces which act among the conductors. Therefore, supports for te conductors can be simplified and their rigidity can be reduced. Cost is thus diminished.
