Ayush Gusain on Instagram: "An eddy current is a loop of electric current induced within a conductor by a changing magnetic field or relative motion between a magnetic field and a conductor, following Faraday's law of induction. Also known as Foucault currents, they are named for the swirling, eddy-like pattern of water. While eddy currents can be undesirable, causing energy loss as heat in devices like transformers, they are also used beneficially in applications such as magnetic braking, induc
