Susceptor heating refers to a technique by which materials that are not electrically conductive may be heated using induction technology. This is done by heating an electrically conductive “susceptor” that then transfers heat to the material via conduction or radiation. The susceptor in this case can be anything from a metallic rod inserted inside of an object, to a metallic pipe with a fluid flowing through it. This is the same technique used in consumer-grade induction cooktops where the pan acts as the susceptor. The cooktop heats the pan via induction, which then transfers the heat to the food via conduction. This same concept can be used to heat an almost infinite variety of materials at large or small scales.
