Unit conversion: 1MHz = 1000KHZ = 1000 000Hz frequency electromagnetic heating Movement: 20 ~ 25KHz IEEE (International Electrical and Electronics Engineers) set for the range: 1, the magnetic field around from about 0.1MHz to 300MHz frequency range, the resulting magnetic induction cooker wholesale factory, its magnetic field strength over 3 gigahertz commercial induction cooker production plants, namely commercial induction cooker factory harmful opportunities, 90MHz to 300MHz magnetic induction cooker factory maximum damage, and heal up closer 0.1MHz hurt smaller field to 0.1MHz injury problem following the magnetic field, the more trivial. Of course, in the scope of its strength in three harmful milligauss following general is regarded as a safe range. Induction cookware uses electromagnetic radiation to heat, electromagnetic radiation at work ordinary cooker coil plate produced in addition to the pot furnace heating surface, there will be a part of the electromagnetic radiation from the body and pot cooker yearning discharge, and generate electromagnetic radiation leakage has been said, this part of the electromagnetic radiation is electromagnetic radiation harmful to human health.
