It might a tiny bit. The magnetic field created by the coil in the stove top will decrease in strength the further away from the coil. So putting for example a tea towel to catch water from the pasta pot under the pot might slightly affect that distance. In practical terms it is not noticeable.

Do you have an idea of how big the effect is then? Below 0,1% efficiency decrease for a thin cotton kitchen rag?

Haha okay ;)

it wouldn't be a loss of efficiency; the energy transfer will always be 100% efficient. It will however reduce the power consumption, as someone else said with a relation ship of inverse square. the material thickness will affect energy transfer by a large amount

further distance between magnetic elements = weaker magnetic force = lower transmission at constant line voltage.

Use pieces of wood of different thicknesses, a set volume of water, and a small pot.

Test & time how long it takes the water to reach a rolling boil.

a difference of 1-3% could be significant in expenses over a year but would be hard to detect reliably in home experiments without going for countless tests

1-3% still isn't much, because that's only the net power used by the induction plate, vs your total daily power usage.

If you have a desktop computer & graphics card, that's probably eating more of your power.

computers lower their consumption when they're not being used to full computational requirements
