​⚙️ How Induction Heating Works

​The core principles involve electromagnetism and resistance:

​Alternating Current (AC) and Coil: A high-frequency alternating current is passed through a coiled conductor (often made of copper, like the one in the picture). This coil is sometimes called the inductor or work coil. ​Magnetic Field Generation: The flowing AC creates a rapidly changing and intense magnetic field around the coil. ​Eddy Currents: When a conductive material (the workpiece) is placed within this fluctuating magnetic field, the magnetic field induces eddy currents (circular electric currents) to flow within the material itself. This phenomenon is described by Faraday's Law of Induction. ​Heating via Resistance: Because the material has electrical resistance, the flow of these intense eddy currents generates heat. This is due to the Joule effect (also known as Joule heating or resistive heating), where electrical energy is converted into thermal energy. ​🔥 Key Advantages

​Induction heating is widely used in manufacturing for processes like melting, forging, welding, and heat treatment because it offers:

​Precision and Localization: Only the target workpiece gets heated, and the heat can be highly localized. ​Speed: It's a very fast heating method. ​Efficiency: It converts electrical energy into heat very efficiently. ​Cleanliness: It doesn't involve combustion, making it a very clean process.
