The lower part of the induction cooker is an electromagnetic transmitter.
When the pot is placed on the induction cooker, the electromagnetic wave emitted by the emitter forms a circular current in the iron pot, and the large current heats the iron pot for cooking.
Possible dangers:
For babies, mobile phones, computers and substations, these electromagnetic waves may cause harm. As for whether these electromagnetic waves will cause harm, it is impossible to have an accurate statement, because no one can do experiments on pregnant women, or even if there is evidence that it will cause harm, it cannot be announced, because we can't stop using mobile phones or substations.
From this point of view, the induction cooker is a very strong electromagnetic emitter (at least 1KW power should be provided). Although a pot absorbs most of the electromagnetic field, the magnetic leakage is certain.
If you are pregnant, don't use the induction cooker.
