Abstract
An isolation magnetic device produced by inserting a first end of a wire through a first hole of a core, wrapping the first end of the wire around a first side of the core and inserting the first end of the wire through a second hole of the core. The second hole of the core is spaced from the first hole and has a longitudinal axis extending parallel to a longitudinal axis of the first hole. The device is further produced by inserting a second end of the wire through the second hole of the core, wrapping the second end of the wire around the first side of the core and inserting the second end of the wire through the first hole of the core.

An isolation magnetic device comprising:
- a core including a first hole and a second hole, the second hole of the core being spaced from the first hole and having a longitudinal axis extending parallel to a longitudinal axis of the first hole;
- and
- a wire having first and second ends,
- the first end of the wire extending through the first hole of a core, around a first side of the core and through a second hole of the core in first direction;
- the second end of the wire extending through the second hole of the core, around the first side of the core and through the first hole of the core in a second direction and wherein a portion of the wire between the first end and the second end is bunched to produce a tap for said isolation magnetic device;
- and
- wherein the wire comprises a first and a second wire;
- and
- wherein the core is a first core, and the device further comprises;
- a second core including a first hole and a second hole, the second hole of the second core being spaced from the first hole and having a longitudinal axis extending parallel to a longitudinal axis of the first hole;
- the first and second ends of the first wire twisted to produce a twisted wire;
