Abstract
Heating element assemblies, heating furnaces incorporating heating element assemblies, methods to form heating element assemblies, methods to form heating furnaces and methods to reduce a magnetic field in a bifilar coil are disclosed. The heating element assembly includes two components, each component formed from heating element wire. The two components are spatially positioned and electrically arranged, relative to each other, so that an electrical current applied to the heating element assembly simultaneously travels through the two components in opposite directions.

A method to reduce a magnetic field in a bifilar coil, the method comprising:
- electrically connecting the bifilar coil to place a direction of current flow in a first section of the coil and a second section of the coil in opposition, the first section and the second section sequentially adjacent in an axial direction of the bifilar coil.
A method of forming a heating element assembly, the method comprising:
- constructing a bifilar helical coil by intertwining two helical components, each helical component formed from heating element wire, wherein the two helical components are spatially positioned and electrically arranged, relative to each other, so that an electrical current applied to the bifilar helical coil simultaneously travels through the two helical components in opposite directions.
A heating element assembly, comprising:
- two components, each component formed from heating element wire,
- wherein the two components are spatially dispersed over the same axis and positioned relative to each other so that an electrical current applied to the heating element simultaneously travels through the two components in opposite directions.
