What Cookware Works on Induction? (2026 Guide)

TL;DR — Induction cooktops only work with magnetic cookware. Cast iron, carbon steel, and magnetic stainless steel work; pure aluminum, copper, and glass don’t (unless they have an added magnetic base). Test with a magnet — if it sticks firmly to the pan’s bottom, it works on induction. The magnet test is the quick answer.

Induction cooktops are efficient and increasingly common, but they’re picky about cookware — only certain materials work. Here’s exactly what does and doesn’t, and how to check. For picks, see our best induction cookware guide.

Why Induction Needs Magnetic Cookware

Understanding how induction works explains the whole compatibility rule in one step.

Induction cooktops heat through magnetism, not a hot surface. Underneath the glass, an electromagnetic coil creates a rapidly changing magnetic field. When you place magnetic (ferrous) cookware on it, that field induces electric currents in the pan itself, and the pan’s own resistance generates heat. The cooktop surface stays relatively cool — the pan is the heat source, not the cooktop.

This is why the cookware must be magnetic: if the pan isn’t ferromagnetic (doesn’t respond to a magnet), the magnetic field can’t induce currents in it, so it won’t heat up at all. The cooktop simply won’t recognize a non-magnetic pan (many display an error or don’t turn on).

So the single rule is: induction requires cookware with a magnetic (ferrous) base. Materials that are naturally magnetic (iron-based) work; materials that aren’t (aluminum, copper) don’t — unless a manufacturer bonds a magnetic layer to the base.

This magnetism requirement is the entire basis of induction compatibility, and it’s why the simple magnet test (below) tells you instantly whether any pan will work. The efficiency benefit of this design — heat generated directly in the pan — is also why induction is fast and energy-efficient. Our best induction cookware guide covers compatible options.

What Works and What Doesn’t

Here’s the practical breakdown of common cookware materials by induction compatibility.

Works on induction (magnetic):

• Cast iron (bare and enameled) — highly magnetic, works great on induction. See our cast-iron guides.
• Carbon steel — magnetic (iron-based), works well. See our carbon-steel guide.
• Magnetic stainless steel — stainless steel with magnetic properties (often labeled induction-compatible, containing magnetic grades of steel or a magnetic base). Not all stainless is magnetic (see caveat below), but induction-ready stainless works.
• Any cookware with an added magnetic base — many aluminum, copper, and nonstick pans have a bonded magnetic (steel) disc on the bottom specifically to work on induction.

Doesn’t work on induction (non-magnetic), unless it has an added magnetic base:

• Pure aluminum — not magnetic; won’t work alone (but induction-ready aluminum with a magnetic base does).
• Copper — not magnetic; won’t work alone (induction copper with a magnetic base exists).
• Glass and pure ceramic — not magnetic; won’t work.
• Some stainless steel — stainless can be non-magnetic depending on its composition (see caveat).

The stainless steel caveat: not all stainless steel is magnetic. Stainless with high nickel content (like some 18/10 austenitic steel) can be non-magnetic, while magnetic grades (or pans with a magnetic base layer) work on induction. This is why you can’t assume all stainless works — you must check. Induction-labeled stainless cookware is made to work.

The universal solution — the magnet test (next section) cuts through all of this: regardless of material or labeling, if a magnet sticks to the bottom, it works. Our best induction cookware and best induction cookware set guides cover verified-compatible options.

How to Check: The Magnet Test

The foolproof way to know if any pan works on induction is simple and takes seconds.

The magnet test: 1. Take a household magnet (a fridge magnet works). 2. Hold it to the bottom of the pan. 3. If the magnet sticks firmly, the cookware is magnetic and will work on induction. 4. If the magnet doesn’t stick (or only weakly), the pan won’t work on induction (or won’t work well).

This test works regardless of the material or what the label claims — magnetism is exactly what induction needs, so the magnet directly tells you. A strong, firm stick means good induction performance; a weak or partial stick may mean marginal or unreliable performance.

Other ways to confirm:

• Look for the induction symbol — induction-compatible cookware is often marked with an induction icon (a coil/loop symbol) or labeled “induction compatible” / “works on all cooktops including induction.”
• Check the product specs when buying — reputable listings state induction compatibility.

Practical tips for induction cookware:

• Flat bottoms work best — induction needs good contact, so warped or ridged bottoms perform poorly.
• Base size matters — the pan’s magnetic base should roughly match the cooktop element size for efficient heating.
• If you’re switching to induction, test your existing cookware with a magnet first — you may need to replace non-magnetic pans (or use an induction interface disk, a workaround that lets non-magnetic pans work, with reduced efficiency).

The bottom line on checking: don’t guess from the material name — do the magnet test. It’s the definitive, instant answer for any pan. When buying new, look for the induction symbol or “induction compatible” labeling. Our best induction cookware guide covers cookware verified to work.

Frequently Asked Questions

What cookware works on an induction cooktop?

Magnetic (ferrous) cookware: cast iron (bare and enameled), carbon steel, magnetic/induction-ready stainless steel, and any pan with an added magnetic base layer (many aluminum, copper, and nonstick pans have this for induction). Cookware that doesn’t work (unless it has a magnetic base) includes pure aluminum, copper, glass, and non-magnetic stainless steel. The rule is that induction heats through magnetism, so the pan must be magnetic. Test any pan with a magnet — if it sticks firmly to the bottom, it works.

How do I know if my cookware is induction compatible?

Do the magnet test: hold a household magnet to the bottom of the pan. If it sticks firmly, the cookware is magnetic and will work on induction; if it doesn’t stick, it won’t work (or won’t work well). This works regardless of the material or label. You can also look for an induction symbol (a coil/loop icon) or “induction compatible” labeling on the cookware or packaging, and check product specs when buying. But the magnet test is the quick, definitive way to know for any pan you already own.

Why doesn’t my cookware work on induction?

Because it’s not magnetic. Induction cooktops heat through a magnetic field that induces currents in ferrous (magnetic) cookware — if the pan isn’t magnetic, the field can’t heat it, so the cooktop won’t work with it (often showing an error). Common non-magnetic culprits are pure aluminum, copper, glass, and some stainless steel (high-nickel stainless can be non-magnetic). Test with a magnet: if it doesn’t stick, that’s why. You’d need magnetic cookware, induction-ready versions with a magnetic base, or an induction interface disk workaround.

Does stainless steel work on induction?

Some does, some doesn’t — it depends on the steel’s composition. Stainless steel with magnetic properties (or a bonded magnetic base) works on induction, and induction-labeled stainless cookware is made to work. But some stainless (high-nickel austenitic grades like certain 18/10) is non-magnetic and won’t work. So you can’t assume all stainless works — test it with a magnet. If the magnet sticks firmly to the bottom, that stainless pan works on induction; if not, it won’t. Look for induction-compatible labeling when buying stainless for induction.

Does cast iron work on induction?

Yes, excellently. Cast iron (both bare and enameled) is highly magnetic (iron-based), so it works very well on induction cooktops and heats efficiently. Its flat, heavy bottom makes good contact with the cooktop. Cast iron is one of the best induction-compatible materials. Just handle it carefully on a glass induction surface — cast iron is heavy and rough, so avoid dragging it (which could scratch the glass); lift it instead. Carbon steel, similarly iron-based, also works well on induction. See our cast-iron guides.

Can I use aluminum or copper cookware on induction?

Not unless it has an added magnetic base. Pure aluminum and copper are not magnetic, so they won’t work on a standard induction cooktop on their own. However, many aluminum, copper, and nonstick (aluminum-based) pans are made with a bonded magnetic (steel) disc on the bottom specifically so they work on induction — these are labeled induction-compatible. Test with a magnet: if it sticks to the base, the pan works despite being aluminum or copper on top. Alternatively, an induction interface disk lets non-magnetic pans work, with reduced efficiency.

The Bottom Line

Induction cooktops only work with magnetic (ferrous) cookware, because they heat through a magnetic field that induces heat in the pan itself. Cast iron, carbon steel, magnetic/induction-ready stainless steel, and any cookware with an added magnetic base work; pure aluminum, copper, glass, and non-magnetic stainless don’t (unless they have a bonded magnetic base). The foolproof check is the magnet test: if a household magnet sticks firmly to the pan’s bottom, it works on induction — regardless of material or label. When buying, look for the induction symbol or “induction compatible” marking. See our best induction cookware and best induction cookware set guides.
