This article describes a technique to measure the temperature of a resistively heated ferromagnetic wire. The wire's temperature rapidly increases, a scenario in which a thermocouple or thermistor's thermal inertia prevents it from keeping up with the rapid temperature variation. The temperature is derived from electrical measurands (voltage and current) and time, as well as thermophysical data such as heat losses and emissivity, and is based on a dynamical thermal–electrical energy conservation principle. We go on to use our technique for the quantitative determination of the Curie point as well as the magnetic susceptibility at elevated temperatures. The results are in good agreement with accepted values.
