Been there done that....
Loved my induction range but my new house has natural gas instead of electric in the kitchen.
As others have commented, do the magnet test. If the magnet sticks it will work. However, there are degrees of "the pan works". The higher the iron content of the steel the BETTER it will work. Do your research before buying.
Gosh Mr. .40 why is that?
Because there are MORE ferrous metal molecules that get all excited when the magnetic polarity changes.
Here is an old thread that I started when I purchased cookware specifically for my induction range. I still use these pans today and have found them to be one of my best ever kitchen purchases.
