Induction stove vs. "normal" cooktop

P.S. One more question. If you react to the electromagnetic field of the stove like that, how do you react to a microwave, a monitor, or a hairdryer? Their electromagnetic field strength is in part several times greater (microwave at one meter distance about 4 times as strong, hairdryer at 30cm distance about 4-5 times as strong).

Did you measure that yourself? Because I’m not quite convinced. A well-known couple once went to the fertility clinic. The man had problems as it turned out. One of the doctors’ questions was whether the man cooked and used an induction field while doing so... If you imagine the height of a countertop, the cooktop is only a few centimeters from the gonads and ovaries. In the extreme, only about 10 cm. At 100 cm distance, you only have (1/10)^2 = 1/100 of the field strength compared to right at the stove. So you must not compare it with that distance, because that would be trivial. The field strength at about 10 cm is what's interesting. And it’s intense! Out of interest, after the conversation I measured the household with a proper EMC meter – router, hairdryer, laptop, oven, microwave, etc. And of course our induction stove. After the stove, there was a long, long gap until the laptop came in a distant second place in the field strength. An induction stove has up to 7000 watts, while even a microwave is at most 800 W – and the microwave has a shielding cage, while the induction stove is "open." In the new house, we then chose a halogen/glass-ceramic cooktop. We also hadn’t quite finished with our family planning yet ;)

I don't want to offend anyone BUT if you can "feel" something besides the issue with the induction field in a microwave, you should actually always have some background noise in your head. Even the wiring in the house emits since it is not isolated.

There are many studies on the subject in which psychological components were also observed - the main tenor: "If they expect a field, so-called electro-sensitive people feel sick."

But in your case, it doesn't matter: If the induction field makes you feel bad, install something else.

Have you measured that yourself? Because I don't really want to believe that.

No, I rely on studies:

An induction cooktop has up to 7000 watts, whereas even a microwave has a maximum of only 800 W - and it has a shielding cage while the induction cooktop is "open".

However, the field is "trapped" exactly there by the appropriate pots, so that less radiation leaks to the right/left etc.

The razor surprises me a lot.

"Tesla" is the unit for the static magnetic field. Even magnetized steel has something like that. However, in all the presented cases of application, we are talking about electrically and magnetically time-varying fields, so there are not only magnetic but also electric flux densities. And very important: power densities, i.e. W/cm2. So this is additionally considered in an analysis, which the little picture does not even address.

And what is further differentiated are the distances. The above diagram: With a microwave, I am hardly 3 cm away from the magnetron, with a drill I will rather hold it 30 cm away from the head, etc.

But for now, let us only consider the magnetic fields:

The ICNIRP guidelines from 1998 determined, based on the investigations published up to that point with a safety factor of 50, a reference value of the magnetic flux density of 6.25 µT.[9] The 2010 guidelines, due to improved data availability from interim publications, were able to reduce the safety factor to 10 and thus set the reference value at 27 µT...

The tested devices complied with the reference value of 6.25 µT of the then applicable ICNIRP guidelines at a horizontal distance of 30 centimeters from the device during intended use, in accordance with the applicable measurement regulations. At realistically smaller horizontal distances, this value was partially exceeded; at a distance of 1 centimeter in front of the device, it reached a maximum of 10 µT, and up to 26 µT at the sides and rear. ... Above the cooktop immediately next to the cookware, significantly higher flux densities of up to 84 µT were measurable. In addition, stronger stray fields arise in cases of improper use through the use of too small cookware or by positioning not centered to the cooking zone, which means the cooking zone is not completely covered, or through the use of cookware with uneven bottoms or those that are not ferromagnetic.

The razor surprises me a lot.

All devices that have motors and possibly also heating coils. I also think that one should distinguish the frequencies here. Personally, I prefer to expose myself to a 1kW 50Hz field rather than a 1kW field in the GHz range :cool:
