Abstract
A method of designing a single- or a multi-phase electric cable for conducting current through insulated conductors and creating a weak external magnetic field, so as to obtain a cable wherein at least one of the above-mentioned conductors is assembled from two or more insulated sub-conductors connected in parallel, and wherein the sum of cross-sectional areas of the sub-conductors is equal to a design cross-sectional area of the conductor. The arrangement in the cable is such that each of the sub-conductors is adjacent to a conductor or a sub-conductor associated with either a different phase or a different current direction, and the sum of magnetic moments of magnetic dipoles formed from all currents passing through the cable is zero.
