Yes, you can test with a magnet. If it doesn’t react, it won’t work. Aluminium for instance doesn’t work.
I don’t know why you were down voted and the user below gave misinformation. I bought a non stick pan before without noticing it wouldn’t work with my induction. Now I bring a magnet when choosing a pan.















It was aldi and not too cheap. But it was a while ago when I induction wasn’t common.
