Magnet, No; Scratch Test

Stainless steel is non-magnetic or only very weakly magnetic. I just tried a fairly strong refrigerator magnet on my stainless steel pots and felt no attraction.
However, aluminum is much softer than stainless steel. If you can easily make a deep scratch, one you can feel with a fingernail, on the bottom or edge of a pan with the point of a sharp knife, then it's almost certainly aluminum. You can feel the blade dig into aluminum; on steel, it will just slide. I just tried this, on both steel and aluminum.
Also, bare aluminum looks dull, like lead, but stainless steel has a metallic, mirror-like luster even when well worn. This is hard to describe. The scratch test is easier to interpret.
Finally, old aluminum pots tend to become pitted. Stainless steel never will.
