1. A method for forming an isolation transformer, the method comprising:
passing a loop forming portion of a primary side wire having a first wire thickness through at least three loop shaped magnetic cores, the at least three loop magnetic cores substantially evenly spaced around a respective portion of the loop forming portion of the primary side wire along a respective circumference of the primary side wire;
passing a loop forming portion of a secondary side wire having a second wire thickness through the at least three loop shaped magnetic cores, the at least three magnetic cores substantially evenly spaced around a respective portion of the loop forming portion of the secondary side wire along a respective circumference of the secondary side wire; and
manipulating each loop forming portion of the primary and secondary side wires passed through the at least three loop shaped magnetic cores to form respective primary and secondary side wire loop portions to provide the isolation transformer.
