Basics of Induction Heating
“Induction heating is a physical phenomenon in the area of electromagnetism. It involves the heating of an electrically conducting object (a metal or a material such as carbon or graphite) by electromagnetic induction. An oscillating magnetic field in an electromagnet, the primary coil, induces so-called eddy currents in a short-circuited secondary circuit. This circuit is the workpiece, i.e. the object to be heated. The eddy currents generate heat against the electrical resistivity of the material. In case the material is magnetic, there is a second effect: magnetic hysteresis losses also produce heat in the object. The amount of heat generated depends on the electric power used to create the oscillating magnetic field, the dimensions and geometry of the workpiece and its material properties, and the coupling between the workpiece and the primary coil that generates the electromagnetic field.”
Some of our customers asked us to educate them on the basics of induction heating. These requests evolved into something we would like to share with the rest of the world as well. A whitepaper giving you more information on the basic principle behind induction heating, the diverse range of applications and advantages, and the different types of equipment you can use to reach your goals.
