A MAGNETIC CORE COMPRISING A HOLLOW CYLINDER OF PERMEABLE MAGNETIC MATERIAL, SAID CYLINDER BEING OF ONE PIECE CONSTRUCTION AND HAVING A PLURALITY OF SPACED SURFACE INTERRUPTIONS ARRANGED IN TWO SEPARATE SERIES OF DIAGONAL ROWS, RESPECTIVELY EXTENDING AROUND SAID CYLINDER IN SUBSTANTIALLY DIAMETRICALLY OPPOSITE DIRECTIONS, THE INTERRUPTIONS IN THE ROWS OF EACH SERIEX BEING INTERPOSED BETWEEN ADJACENT SPACED INTERRUPTIONS IN CORRESPONDING ROWS OF THE OTHER SERIES, IN SPACED, ANGULAR RELATION THERETO, DEFINING THEREWITH, ON THE SURFACE OF SAID CYLINDER, THE RESPECTIVE BOUNDARIES OF TWO SETS OF STAGGERED, INTERSECTING PATHS FOR THE FLUXES RESPECTIVELY PRODUCED BY A LONGITUDINAL AND AN ANNULAR MAGNETIC FIELD, THE INTERRUPTIONS OF EACH ROW OF EACH SERIES LYING SUBSTANTIALLY CROSSWISE TO THE DIRECTION OF TRAVEL OF SAID FLUXES ALONG RESPECTIVE PATHS, TO DIVERT SAID FLUXES AND PREVENT THE FLUX PRODUCED BY A LONGITUDINAL MAGNETIC FIELD FROM INTERSECTING AT SUBSTANTIALLY RIGHT ANGLES, THE FLUX PRODUCED BY AN ANNULAR MAGNETIC FIELD, AT ANY POINT ON SAID CYLINDER.
