Experimental studies have been carried out in order to examine the applicability of Lavers' model to the electromagnetic fields in the laboratory-scale induction furnace with high frequency. The furnace used is made of 14 turn 0.054m-radius and 0.14m-height induction coil and power supply with frequency of 9.09kHz or 480kHz. Magnetic flux densities have been measured under the conditions without load, with a long copper cylinder load, and with a mercury pool load, respectively. These values have been well consistent with Lavers' model. Joule's heats have been measured for the following metals : copper, zinc, tin, lead and mercury. These values have been well consistent with the model in the range of r_1/δ from 4 to 100, where r_1 is the radius of load and δ is the skin depth. From these results it is possible to apply Lavers' model to the electromagnetic fields in molten iron in a laboratory-scale induction furnace.
