Abstract: The aim of this paper is to clarify the mechanisms of heat generation in metallic pipes housing AC power cables. While many researchers—including some IEEE reviewers—attribute this phenomenon primarily to Joule heating, the experiments conducted in this research demonstrate that eddy currents are the principal cause of temperature rise in iron pipes surrounding AC conductors. The paper examines the fundamental principles of electromagnetic induction, tracing its historical development through a sequence of landmark experiments ranging from the era of Michael Faraday to Samuel Morse. This research serves as a modern follow-up to that historical lineage, providing empirical evidence to distinguish between induction-based losses and standard Ohmic heating.
