How does choosing good induction cookware differ from choosing cookware for other types of stove? Let me just clarify I'm not asking for specific brands, but features.

We just got an induction stove and I want to pick up some new pots/pans etc. I know that I have to pick induction-safe materials. But beyond that, is there anything to consider different from the considerations when buying pans and pots for a gas or resistive stove?
The things you need in a good induction pan are:


The metal must be iron/steel, because induction stoves work using magetic fields
they need a good sized flat section on the bottom, this is so that the material of the pan is as close to the field generator in the stove


When shopping for induction pans bring a magnet, if it sticks to the bottom of the pan it should work on your induction stove.
