-11- Abstract of the Disclosure: A method of making a magnetic core from amorphous strip material for use in a transformer or like electrical In- duction apparatus is disclosed herein. In accordance with this method, a continuous strip of non-annealed amorphous metal is wound around a mandrel to form an initially round core which is clamped in a predetermined way and cut en- tirely through one transverse section while a rust inhib- iting liquid coolant is applied thereto. This provides a plurality of connected strips which are thereafter separated into a number of groups and assembled together in a pre- determined way to form a substantially oval shaped core. This latter core is formed into final shape and thereafter annealed and simultaneously subjected to a magnetic field of predetermined strength in preparation for receiving an associated electric coil or coils.
