EDDY CURRENT Meaning and
Definition
-
Eddy current refers to a phenomenon that occurs when a conductor, typically a metal, is exposed to a changing magnetic field. It is characterized by the induction of small circulating currents within the conductor, which are known as eddy currents. These currents create their own localized magnetic fields that oppose the initial changing magnetic field, resulting in resistive heating of the metal.
Eddy currents are caused by Faraday's law of electromagnetic induction. When a conductor is exposed to a changing magnetic field, such as when it moves through or is subjected to alternating current, the magnetic field induces these looping currents within the conductor. The magnitude and direction of the eddy currents depend on factors like the size, shape, and conductivity of the conductor, as well as the strength and frequency of the changing magnetic field.
The presence of eddy currents can have both advantageous and disadvantageous effects. In some applications, such as in induction heating or magnetic braking systems, the resistive heating produced by the eddy currents is intentionally utilized for practical purposes. Conversely, in electrical transformers or other devices, eddy currents lead to power losses and energy dissipation, which are considered undesirable.
Efforts to minimize or mitigate the effects of eddy currents include using laminated cores made of thin sheets of metal in transformers or employing magnetic shielding materials to confine the magnetic field. These techniques effectively reduce the circulation path of the eddy currents, minimizing power losses and improving device efficiency.

Etymology of EDDY CURRENT
The word "eddy" comes from Middle English "edy", which means "a whirlpool or a current moving in a circular motion". It originated from the Old English term "ed-ēa" or "edd-ēa", where "ed" refers to "turning" and "ēa" means "water" or "river". The term "eddy current" was coined in the 19th century by the Scottish physicist James Clerk Maxwell. He used "eddy" to describe the circular circulating currents that are generated when a conductor is exposed to a varying magnetic field. These currents are also known as "Foucault currents" after the French physicist Léon Foucault, who conducted extensive research on them.
