ABSTRACT:
An electrical inductive apparatus such as a transformer including a magnetic core and an associated electrical coil is disclosed herein along with various methods of assembling the coil around the core. In each of the various embodiments disclosed, the core itself is one which is initially formed from a continuous strip or strips of amorphous material formed to provide a closed loop which is thereafter annealed but before its coil is assembled thereto. Various techniques are disclosed for winding the coil around a corresponding section of the core.
