Summary
[edit]DescriptionFoil on induction cooktop.jpg |
English: Aluminum foil on an induction cooktop (hob). Household aluminum foil is much thinner than the skin depth in aluminum at 24 kHz, typical of the frequencies used by induction cooktops. It will heat up on a cooktop. This foil had a steam bubble form below water, and when the foil was exposed to air, it melted through. Since aluminum is not ferromagnetic, hysteresis does not contribute to the heating effect. Manufactures of cooktops recommend not using aluminum on induction cooktops. |

Taken on the middle burner of a GE Profile induction top at maximum power. Do not attempt this - I risked my cooktop so that you don't have to risk yours.
