Power Dissipation of Eddy Currents

Eddy currents are circulating electric currents induced in conductors due to a changing magnetic field. These currents generate resistive heating, leading to energy dissipation. Understanding the power loss due to eddy currents is crucial in applications such as electrical machines, transformers, induction heating, and electromagnetic shielding. This article derives the formula for power dissipation per […]

Eddy Currents and the Lorentz Forces

Eddy currents are circulating currents induced within conductors when they experience a changing magnetic field. These currents arise due to electromagnetic induction, following Faraday’s Law, and are opposed by Lenz’s Law, which states that the induced current will flow in a direction that opposes the change causing it. This phenomenon is particularly significant in electrical […]
