A pan is induction compatible if a magnet sticks firmly to its base, because induction cooktops only heat magnetic metals like cast iron and magnetic stainless steel. Aluminum, copper and glass do not work unless they have a magnetic base layer. Look for the induction coil symbol on the pan too.
Hold a magnet to the bottom of the pan. If it grips firmly, the pan works on induction. Cast iron and magnetic stainless steel pass; plain aluminum, copper and glass do not unless they have a magnetic base.
How to Check Compatibility
The magnet test
Induction works by creating a magnetic field, so the pan base must be magnetic. If a fridge magnet sticks firmly to the bottom, the pan will work. A weak or no grip means it will not.
The induction symbol
Many pans stamp an induction mark, a coil of loops, on the base or box. Its presence confirms compatibility without a magnet.
Which materials work
Cast iron, carbon steel and magnetic stainless steel work. Plain aluminum, copper, glass and some non-magnetic stainless do not, unless the maker adds a magnetic disc to the base.
How to Test Your Pan
- Take a common fridge magnet.
- Hold it against the center of the pan base.
- If it sticks firmly, the pan is induction compatible.
- If it does not stick or only weakly grips, it will not work on induction.
- Check the base and packaging for the induction coil symbol to confirm.
Induction Compatibility by Material
| Material | Induction compatible? |
|---|---|
| Cast iron | Yes |
| Carbon steel | Yes |
| Magnetic stainless steel | Yes |
| Aluminum | Only with a magnetic base |
| Copper | Only with a magnetic base |
| Glass and ceramic | No |
Common Mistakes to Avoid
- Assuming all stainless steel works; some is non-magnetic and will not.
- Buying aluminum or copper pans for induction without a magnetic base layer.
- Ignoring the induction symbol printed on the pan or box.
When to Consider a Replacement
If your favorite pans are not induction compatible and you have an induction cooktop, you will need magnetic cookware. See induction-ready sets in our guide to the best cookware sets, or the naturally magnetic best cast iron skillets.
Frequently Asked Questions
Does the magnet test really work for induction?
Yes. Induction only heats magnetic metal, so if a magnet sticks firmly to the pan base, the pan will work. It is the quickest reliable test.
Is all stainless steel induction compatible?
No. Only magnetic stainless steel works. Some stainless is non-magnetic and will not heat on induction, so always do the magnet test.
Can I use aluminum pans on an induction cooktop?
Only if they have a magnetic base layer added by the maker. Plain aluminum is not magnetic and will not work on induction.
