A wire-based heating element is provided having first and second portions twisted about each other such that magnetic flux emitted from one portion is substantially cancelled by magnetic flux emitted from the other portion. A bonding material that fixedly connects the two portions of the heating ele
A wire-based heating element is provided having first and second portions twisted about each other such that magnetic flux emitted from one portion is substantially cancelled by magnetic flux emitted from the other portion. A bonding material that fixedly connects the two portions of the heating element and restricts their movement relative to each other to thereby maximize the cancellation of magnetic flux. A substrate-based heating element is also provided having traces on opposed sides of a substrate and overlying each other to cancel magnetic flux. Electrical connection pads are located on the same side of the substrate, and the second trace extends passed the first trace to connect to the second connection pad. A lead connected to the first connection pad overlies the portion of the second trace that extends to the second connection pad to thereby cancel magnetic flux emissions from this portion of the second trace.
