    • Abstract:
      In this experiment Nickel and Kanthal-A wire were heated through resistive heating to find their respective Curie temperatures. High electrical current passed through the wires to heating them to temperature where the materials lost their ferromagnetic properties, becoming paramagnets, shown physically by disconnecting from a permanent disc magnet. The Nickel wire was found to have a Curie temperature of 343.33 °C and it reached this in 40 seconds when the voltage source was set to 10 V. Kanthal-A was unable to be heated to the expected Curie temperature due to the physical power limitations of the circuit. The experimental Curie temperature for Nickel did agree with the theoretical temperature of 350 °C and any discrepancies are attributed to the manual method of current increase.
