Pans with iron are a requirement for induction. You cannot use aluminum or copper.
edit: Here's an article about what pots will work with induction. Spruce Eats usually does a pretty good job with their research and articles.

As I said, my experience with induction is pretty limited. I can tell you that I passed along a couple of stainless steel sauce pans that I no longer wanted to a friend a few years back; she was moving to a house she had built in Washington and had included an induction range in her kitchen. One pot was a small cheapo Wolfgang Puck and the other was an AllClad sauteuse. Huge difference in price and quality. Both performed fine for me on my gas cooktop but she said that the All Clad was fabulous on her induction cooktop but that the Puck didn't work nearly as well and she got rid of it. I have no clue why one worked and the other didn't. The only thing I can think of is that the Puck, while stainless on the outside, had some kind of core on the bottom. I don't know what the core was made of. The AllClad was solid stainless.
Cast iron is actually perfect for induction. It's just too heavy for Mr wtg to use; he has pretty severe arthritis in his hands and also had carpal tunnel surgery a couple of years ago.
