It’s not ferromagnetic but it still interacts with the induction coils - if you’re willing to risk burning out your cooktop through abuse, you can magnetically levitate a ring of aluminum foil on it.

Are you sure it was a genuine aluminium pan? The stove would have to be able to reach 933.47 K ​/ 660.32 °C / ​1220.58 °F, which most won’t get anywhere near that. A propane stove might, but an electric stove is unlikely to get so hot.

I’ve done cooking & baking classes at a community house and we used the Ikea “365” range of stainless steel pots and pans, with metal lids. They’re fairly cheap but induction compatible and stand up to a fair amount of abuse.
