We would need a diagram of the specific induction cooker to calculate this because you have to know the distance from the coils to the pan

Generally though, the dirt at the bottom shouldn’t matter. They’re generally at the micron level of thickness

hwo about the kitchen towel?


MrMuf t1_jbaekvx wrote

Kitchen towel is not a good example since it comes in many shapes and sizes. Also it compresses down depending on the weight on top of it. Also the risk of fire. If you want to cover the pan, use silicone or something

From one pic I’ve seen, it seems that the cover is pretty much on top of the coils.

The mutual inductance change ratio it does will be (r_initial/r_final)^2 If the towel is the same thickness as the cover, this’ll be r_final=2*r_initial (1/2)^2=1/4 whichll mean 1/4 the power

If the cloth is half the thickness of the cover, then r_final=1.5*r_initial (1/1.5)^2=.44

If the cloth is 1/8th the thickness, it’ll be 80% the same efficiency

I’ve seen silicone mats for this purpose to prevent scratching of the cooktop. Never tested them myself though

i've seen some mats made for induction cooking on amazon. however, some reviews talking about them melting (which results not just in money loss of item, but very hard or impossible to remove stain on the expensive stovetop).

now, some reviews are likely to be from ill informed people with an electric stove. however, some claim to be certain that they have induction stove and they still melted, which worries me.
