Induction cooktops require ferromagnetic pans; test with a magnet.
- Cast iron and most stainless steel work; aluminum, copper, and glass do not.
- Look for 'induction ready' labels or symbols on cookware.
- Flat-bottomed pans ensure even heating and prevent surface damage.
How Induction Cooking Works
Induction cooktops use electromagnetic coils beneath a glass surface. These coils create a magnetic field. The field induces electric currents in the pan's base. Those currents generate heat directly in the metal. The cooktop surface stays cool, only the pan heats. This makes induction fast and efficient. It also means the pan must be ferromagnetic.
What Pans Work on Induction Cooktops
Cast iron pans work perfectly, including enameled cast iron. Most stainless steel pans with a magnetic bottom work too. Look for a label saying 'induction ready' or 'induction compatible.' Some stainless steel contains nickel, which is magnetic. If a magnet sticks, it works. Carbon steel and magnetic steel are also good. Check the base with a magnet to be sure.
Which Pans Do Not Work
Pure aluminum pans do not work because they are not magnetic. Copper pans also lack magnetism. Glass and ceramic cookware are non-magnetic. Most nonstick pans with aluminum bases fail the magnet test. Some brands add a magnetic layer to the base. Avoid pans with a wobbly or warped base. They can scratch the glass surface.
How to Test Your Existing Pans
Use a small magnet to test each pan. Place the magnet on the bottom of the pan. If it sticks firmly, the pan is induction-compatible. If it sticks weakly, it may still work but slower. If it does not stick, the pan will not heat. You can also check the pan's packaging or manufacturer website. Many brands list induction compatibility.
Best Cookware Types for Different Needs
For everyday cooking, stainless steel with an aluminum core heats evenly. Cast iron retains heat well for searing and frying. Enameled cast iron is great for slow cooking and looks nice. For lightweight needs, choose induction-ready nonstick pans. They have a magnetic stainless steel base. For large pots, ensure the base diameter matches the burner size. Small pans may not trigger the sensor.
