Eddy currents are swirling currents of electricity that circulate within conductive materials when they are exposed to changing magnetic fields. Imagine a tiny whirlpool of electricity dancing through a metal sheet when a magnet moves nearby. These currents are not something we can see with our naked eyes, but they sure do exist. To understand the concept better, let us break it down. When a magnetic field<\/strong> changes near a conductive material like metal, it induces an electric current within that material. This current then creates its own magnetic field, which opposes the original change in the magnetic field that induced it. It\u2019s like a game of tug-of-war between magnets, but with electricity involved! In this blog, let us get to know what is Eddy Current along with its usage to us.<\/p>\n\n\n\n\n\n\n

What is Eddy Current?<\/h2>\n\n\n\n

The name \u201ceddy\u201d comes from their resemblance to whirlpools or eddies in a stream. Eddy currents are named because of the current\u2019s eddy-like appearance. These currents were first described by French physicist L\u00e9on Foucault in 1855<\/strong>.<\/p>\n\n\n\n

Foucault\u2019s definition emphasizes the dynamic nature of these currents and their relationship to magnetic field variations. Foucault\u2019s experiments focused on the specific phenomenon of these induced currents flowing in closed loops within the conductor itself, rather than in an external circuit. Thus, eddy currents are also known as Foucault\u2019s currents.\u00a0<\/p>\n\n\n\n

Definition of Eddy Currents: Eddy currents are circulating electric currents induced within a conductor by a changing magnetic field.<\/strong><\/p><\/blockquote><\/figure>\n\n\n\n

These currents flow in closed loops within the conductor, resembling whirlpools or eddies in a stream. They arise because the changing magnetic field disrupts the motion of electrons in the conductor, causing them to move in circular paths.<\/p>\n\n\n\n

However, The concept of what is eddy currents likely stemmed from the well-established principle of electromagnetic induction, which was discovered by Michael Faraday in 1831.\u00a0<\/p>\n\n\n\n

Eddy current refers to an induced current that is generated in a conducting coil as a result of a change in the magnetic flux. According to Faraday\u2019s laws of induction, eddy currents flow in closed loops and in planes that are perpendicular to a magnetic field. When an electromagnet is connected to a battery, it will generate a current in a magnetic field. This current will also induce an eddy current on a magnetic plate. The induced current will take the form of an eddy in the plate. It is also called \u201ceddy currents\u201d because they form in the shape of whirlpools or in the shape of eddies in water.\u00a0<\/p>\n\n\n\n

Eddy current is present in every solid and is one of the basic properties of solid conducting bodies. When the magnetic flux of a conductor changes, the free electrons in the conductor become subject to a sudden magnetic force. This force causes the free electrons to move in the form of small eddies.<\/p>\n\n\n\n
