It is to generate eddy current on the metal pot to achieve the purpose of heating, not.
electromagnetic radiation
Can't heat. It is not surprising that the publicity of manufacturers is always half-delayed, or partially enlarged.
Their practice is basically to form a shield between the bottom of the pot and the edge of the induction cooker body. The grounding of the shield (power supply grounding) can play a certain role in the electromagnetic leakage of the induction cooker, but it is ignorant to say zero radiation.
Radiation is in different frequency bands. There is still a gap from this shield. The low frequency band can be intercepted, and the high frequency harmonics are more difficult. Moreover, any electromagnetic test equipment has a background and cannot be directly subtracted. if
Measurement data
Close to the background, not 0, can only say that it is very small. Besides, if they publish a full-band
measuring result
Convincing.
