Foucault current, also known as eddy current or parasitic current, refers to a phenomenon where circulating currents are induced in a conductor when it is subjected to a changing magnetic field. Synonyms for this term are important for deepening our understanding of this concept. Some alternative terms that can be used interchangeably with Foucault current are induced current, swirling current, and vortex current. These synonyms help describe the nature of the current that is generated and emphasize the circular or swirling motion that occurs within the conductor. Exploring these synonyms assists in expanding our knowledge of this vital aspect of electromagnetism and its practical applications in various fields such as electrical engineering and physics.
