What Pans Work on an Induction Burner? A Plain-English Guide
Induction only heats magnetic cookware, so the pan you grab matters more than you might think.
Plug in a new induction burner, set a pot on it, and nothing happens. That is the most common complaint from first-time induction users, and the fix is almost always the same: the wrong pan. Induction cooktops heat cookware by creating a magnetic field, so only pots and pans that contain iron or steel in their base will work. The good news is that you can test every pan in your kitchen in about ten seconds, and most people already own at least a few that are compatible.

How Induction Actually Heats a Pan
A standard electric burner glows hot and transfers heat through direct contact. An induction burner works completely differently. It sends an alternating electric current through a coil beneath the glass surface, which creates a rapidly changing magnetic field. When a pan made of a magnetic material sits on that field, tiny electric currents form inside the metal itself and generate heat directly in the pan. The glass surface barely gets warm on its own. This means if a pan cannot interact with the magnetic field, no heat is produced at all, no matter how high you set the power level.
Pans That Work: Magnetic Metals
Cast iron is the most universally compatible material. Flat-bottomed cast iron skillets and Dutch ovens work on every induction burner without any caveats. Carbon steel pans are equally compatible and tend to heat very evenly. Stainless steel cookware is where things get a little more complicated: stainless steel blended with iron or nickel (most common grades) is magnetic and will work, but some high-end stainless steel pans use alloys that are not magnetic and will not. Enameled cast iron, like a colorful Dutch oven, also works fine because the iron core is still magnetic underneath the enamel coating.
Pans That Do Not Work: Non-Magnetic Materials
Aluminum pans, copper pans, and glass or ceramic cookware are not magnetic and will not work on an induction burner. This catches a lot of people off guard because aluminum and copper are popular for everyday cooking. Pure aluminum pans, thin non-stick skillets with aluminum bodies, and copper saute pans will all produce zero heat on an induction surface. Some manufacturers get around this by bonding a magnetic stainless steel disc to the bottom of an aluminum pan, and those pans will work. Check for a label that says "induction compatible" before assuming an aluminum pan will function.
The Magnet Test: Check Your Pans in 10 Seconds
You do not need to guess. Hold a refrigerator magnet against the bottom of any pan. If the magnet sticks firmly, the pan will work on induction. If it slides right off or barely clings, set that pan aside for a gas or electric coil burner. A strong pull means good induction performance. A weak pull usually means there is some magnetic material but not enough to heat efficiently, so you may get sluggish heating or an error code on the burner. This test works on every pan you own and takes no special knowledge.
Flat Bottoms Matter as Much as Material
Even if your pan passes the magnet test, a warped or rounded bottom will reduce performance. Induction relies on close contact between the pan base and the cooktop surface. A bowed or warped pan creates an air gap, which weakens the magnetic coupling and slows heating. This is why older cast iron pans that have been dropped or roughly used sometimes underperform on induction. When shopping for new cookware to use with an induction burner, look for pans described as having a flat, impact-bonded, or disc-bottom base. These terms all indicate that the manufacturer designed the pan to make consistent, full contact with a flat cooktop.
Pan Size and Burner Size
Most portable induction burners have a coil that spans roughly 6 to 8 inches. If you use a pan that is significantly smaller than the coil, the burner may not detect it and will display an error or shut off. If you use a pan that is much larger than the coil, only the center of the pan will heat well and the edges will stay cool. The best results come from matching your pan diameter to the coil size as closely as possible. For a single-burner unit like the duxtop BT-180G3 or the Nuwave PIC FLEX, a 10-inch or 12-inch skillet is usually the sweet spot that heats evenly from edge to edge.
What to Buy If You Need Compatible Cookware
If your current cookware fails the magnet test, you do not need to replace everything at once. A single flat-bottomed cast iron skillet in the 10 to 12 inch range covers most everyday cooking and costs less than many non-stick pans. A 3 to 4 quart carbon steel saute pan adds sauce and pasta capability. If you prefer non-stick, look for brands that specifically label their products as induction-ready, since these include a bonded magnetic base. Avoid sets marketed only as "PFOA-free" or "ceramic-coated" without any mention of induction compatibility, since those descriptions say nothing about the base material.
Frequently asked questions
Will my non-stick pan work on an induction burner?
It depends on what the non-stick pan is made of underneath the coating. Many non-stick pans have aluminum bodies, which are not magnetic and will not work. Some non-stick pans are made with a stainless steel or iron base and are labeled induction-compatible. Run the magnet test on the bottom of your specific pan to find out.
Can I use a cast iron skillet on a portable induction burner?
Yes, cast iron is one of the best materials for induction cooking. It is highly magnetic and retains heat well. Just make sure the bottom of the skillet is reasonably flat and not badly warped. Flat-bottomed cast iron pans work with virtually every portable induction burner on the market.
My induction burner shows an error when I put my pan on it. What does that mean?
An error or blinking light usually means the burner cannot detect a compatible pan. First, check that your pan passes the magnet test. If it does, the pan bottom may be too small for the coil, or the pan may be warped and not making good contact with the surface. Try a different pan to see if the error goes away.
Does the induction burner damage non-magnetic pans?
No. Placing a non-magnetic pan on an induction burner will simply produce no heat. The pan will not be damaged, and neither will the cooktop. The burner will usually display an error message or turn itself off after a few seconds of detecting no compatible cookware.
Is stainless steel always induction-compatible?
Not always. Most everyday stainless steel cookware uses an iron-containing alloy that is magnetic and will work on induction. However, certain high-alloy stainless steels used in professional or restaurant cookware are not magnetic. Always check with the magnet test or look for an induction-compatible label on the packaging before buying.
