What Pans Work on Induction Cooktops?
A plain-English guide to which pots and pans your induction cooktop will actually heat.
Induction cooktops are fast and efficient, but they're picky about cookware. Unlike gas or radiant electric, induction heats the pan itself through a magnetic field, so the pan has to be magnetic to work at all. The good news is that most kitchens already have at least a few compatible pieces, and checking is easy.
How Induction Actually Heats a Pan
An induction burner uses a coil under the glass that creates a rapidly changing magnetic field. When you set a magnetic pan on top, that field induces electric currents inside the metal, and those currents heat the pan directly. The glass surface stays relatively cool because it isn't the heat source. This is why induction only works with pans that respond to a magnet; if the field can't grab the metal, no heat is produced.
The 30-Second Magnet Test
The simplest way to check any pan is to hold a kitchen magnet against the bottom. If it sticks firmly, the pan will almost certainly work on induction. If it only weakly clings or falls off, the cooktop may not recognize it or may heat it unevenly. A refrigerator magnet works fine for this. Test the center of the base, since some pans have a magnetic disk that doesn't cover the whole bottom.
Materials That Work and Materials That Don't
Cast iron, enameled cast iron, carbon steel, and most magnetic stainless steel pans work well on induction. Aluminum, copper, glass, and ceramic cookware will not work on their own because they aren't magnetic. Some stainless steel is non-magnetic too, which is why the magnet test matters more than the label. Many newer pans are sold as 'induction-ready,' meaning a magnetic layer has been bonded into the base.
Pan Size and Flatness Matter Too
Even a magnetic pan can underperform if it's the wrong size or shape for the burner. Most induction elements need the pan base to cover a minimum diameter, or the cooktop won't switch on. A warped or rounded bottom also reduces contact and can cause hot spots or error beeps. For best results, match your pan diameter to the cooking zone and use flat-bottomed pieces.
Options If Your Cookware Isn't Compatible
If your favorite pans aren't magnetic, you don't necessarily have to replace everything at once. An induction interface disk sits between the burner and a non-magnetic pan, though it adds bulk and slows things down. Otherwise, building up a few induction-ready core pieces over time is usually the better long-term move. A portable single-burner induction unit, like the Duxtop BT-200TI, is a low-cost way to test induction cooking before committing to a full cooktop.
Built-In Induction Cooktops to Consider
If you're sold on induction, a built-in unit gives you multiple zones and a clean glass surface. The Frigidaire FGIC3066TB is a 30-inch, four-element induction cooktop that has drawn a large number of customer reviews. The Nuwave PIC Gold Pro is a compact single-burner countertop option for smaller kitchens or as a backup burner. Either way, plan to use magnetic cookware from day one so you get the speed induction is known for.
Frequently asked questions
Will my old stainless steel pans work on induction?
Some will and some won't, because stainless steel can be magnetic or non-magnetic. Hold a magnet to the bottom; if it sticks firmly, the pan is induction compatible.
Can I use cast iron on a glass induction cooktop?
Yes, cast iron works great on induction. Just set it down gently and avoid sliding it, since the rough base can scratch the glass surface.
Why won't my induction cooktop turn on with a certain pan?
The pan is likely non-magnetic or too small to be detected. The burner needs a magnetic base that covers the cooking zone's minimum diameter before it will start heating.
Do I need special induction pans, or can I adapt my current ones?
You can use any magnetic pan you already own. For non-magnetic favorites, an induction interface disk lets them work, though it's slower than buying induction-ready cookware.
