Abstract

A magnetic core for an electric coil is made from a rectangular (iron) sheet in which is formed a plurality of parallel slits extending laterally across part of the width of the sheet, the sheet then being folded concertina-fashion along the lines of the slits so that adjacent sections of the sheet are in facial contact. The slits preferably extend parallel to the shorter side and across the middle portion of the sheet (Fig. 1, not shown), the folds being made in the portions left at either end of each slit. The slits may be so spaced that the assembled core has an approximately circular cross-section. The sheet is coated with insulating material before it is folded.
