| Popis: | Recently, induction heating (IH) ranges, which heats using Joule heat based on eddy currents in a pan, have been increasing not only for household use but commercial use. Some of users have concerns about the possible health effects of magnetic fields from induction heating ranges. In this study, we quantitatively measured leakage magnetic fields from an IH range as a survey range. Especially, we investigated the effect of the size of a pan. The magnitudes of the measured magnetic field at the edge were 5–40 µT, depending on the size of the pan used. Furthermore, the magnitudes were inversely proportional to the cubic of the distance from the edge of the range, which indicated that leakage magnetic fields from IH range can be expressed as a magnetic dipole moment. The magnetic fields increased when the size of the pan was smaller, since much magnetic fields may leak from the operating coils. |
