A device is described for magnetic heat induction and subsequent heat exchange to mobile streams of matter. The device can provide efficient heating of moving gaseous, liquid, or solid masses. A cold mass is made to flow past an induction heated workpiece, whereby the cold mass becomes heated via thermal transfer from the workpiece to the cold mass. The device can include a material susceptible to heating by magnetic induction that is inserted into a tube or other containment structure. The tube can be the transport conduit for the material to be heated. An induction coil can surround the tube. The coil can be connected to a high energy LC (inductance-capacitance) resonance circuit. Resonance generates magnetic flux in the coil. The flux can interact with the workpiece inside the tube. Heat can be generated in the workpiece and can then be transmitted to the cold mass as it is conveyed past the workpiece.
