Plural leg laminations of equal length are stacked in two groups having concealed stepped-lap joint halves at one ends and visible stepped-lap joint halves at the other ends. Plural yoke laminations of incrementally varying lengths are stacked in a first group having visible stepped-lap joint halves at each end and a second group having concealed stepped-lap joint halves at each end. A rectangular magnetic core is assembled by mating the visible joint halves of the first yoke group and the concealed joint halves of the two leg groups, and then mating the visible joint halves of the leg groups with the concealed joint halves of the second yoke group.
