I just added a white paper explaining the change of resistance method for temperature measurements on magnetics (transformers and inductors). This is especially useful if for some reason the sample is difficult to attach a thermocouple or the thermocouple goes a bit crazy when exposed to strong magnetic or high voltage fields. This is especially useful when the physical construction prevents the addition of a thermocouple within the windings.
I consider this a last resort solution after shielding and ferrite beads on thermocouples just won’t work.
