I was looking into getting a portable induction burner.

Magnet test for stainless steel.

There are three. Place the magnet on the sample and tip it upright or try to pull the magnet away from the metal. The magnetic response of a piece of steel is a quick and qualitative test that can be useful for sorting grades of stainless steel. Other qualitative tests are listed in atlas technote 1.

Metals can be classified as ferromagnetic paramagnetic or diamagnetic. The following types of stainless steel are typically magnetic. The magnet did not stick. If the magnets attaches to the grill then it is not made of high grade stainless steel.
