If you've switched to an induction range and had a pan just sit there doing nothing, you've already learned the core rule the hard way: induction doesn't care what a pan is called, only whether it's magnetic. This guide covers what actually determines compatibility, how to check what you already own, and where to look before buying anything new.
Anyone who's recently switched to induction and isn't sure which pans still work, or is buying new cookware and wants to avoid surprises.
It explains what actually matters — magnetic content, not the material name on the box — and gives a one-second test with a magnet.
If you're not on induction and don't plan to be, this is a compatibility guide specifically, not a general recommendation.
Induction cooktops heat cookware directly through a magnetic field, so only cookware with enough iron content to respond to that field will work — the material name on the box matters less than whether it's actually magnetic. Cast iron and carbon steel work reliably. Some stainless steel works and some doesn't, depending on its exact alloy. Pure aluminum, copper, and glass don't work at all unless a magnetic layer has been bonded to the base. The fastest way to know for certain: stick a magnet to the bottom of the pan.
How induction actually decides what works
An induction cooktop doesn't heat up the way a gas or electric burner does. It generates an electromagnetic field, and that field only creates heat inside cookware that's magnetic enough to respond to it — the heat is generated directly in the pan itself, not transferred from a hot burner underneath. That's why a perfectly good pan can sit on an induction cooktop and do nothing: if it isn't magnetic, the field has nothing to act on.
You can't judge compatibility by material name alone. "Stainless steel" isn't automatically induction-compatible; it depends on the specific alloy. A pan can be labeled "aluminum" or "copper" and still work fine on induction, as long as the manufacturer bonded a magnetic layer to the bottom specifically for that purpose.
Which materials actually work
| Material | Induction compatible? | Why |
|---|---|---|
| Cast iron (bare or enameled) | Yes, reliably | Naturally magnetic — commonly cited as one of the best-performing materials on induction |
| Carbon steel | Yes, reliably | Naturally magnetic, same as cast iron |
| Stainless steel | Depends on the alloy | Only stainless with enough iron content is magnetic — check the specific product rather than assuming |
| Pure aluminum | No, unless modified | Not magnetic on its own — needs a bonded magnetic base layer to work |
| Pure copper | No, unless modified | Same as aluminum — needs a bonded magnetic base layer |
| Ceramic-coated cookware | Depends on the base metal | The coating itself doesn't determine compatibility — it's whatever magnetic (or non-magnetic) metal sits underneath it |
| Glass | No | Not magnetic, no exceptions |
The magnet test: stick a refrigerator magnet to the bottom of the pan you're checking. If it holds firmly, the pan is induction-compatible. If it slides off or barely attracts at all, it isn't. Test the actual cooking surface on the bottom, not the handle — a stronger magnet gives a clearer result, but a standard fridge magnet is usually enough to tell.
What to check before buying new induction cookware
Look for "induction-compatible" stated explicitly on the product listing rather than assuming based on material alone, since the same material name can mean different things depending on the specific alloy or construction. Many manufacturers also stamp a small coiled-spring symbol on the bottom of induction-ready cookware — useful as a secondary check, though the magnet test remains the most reliable one you can do yourself. If you're buying a multi-piece set, it's worth confirming every piece is induction-rated individually rather than assuming the whole set qualifies just because one piece does.
Where to start if you're shopping
Since cast iron, carbon steel, and much of stainless steel are already reliably induction-compatible, the most direct path is choosing from materials this site already covers in depth, then confirming the specific product with the magnet test or the manufacturer's induction rating:

Best for
Anyone who's recently switched to an induction range and isn't sure which of their current pans still work, and cooks buying new cookware who want to avoid discovering incompatibility after the fact.
Maybe skip if
You're not on induction and don't plan to be — this is a compatibility guide specifically, not a general cookware recommendation, and the same pans that work great on gas or electric may need nothing special at all.
Frequently asked questions
How do I know if my current cookware works on induction?
Stick a magnet to the bottom of the pan. If it holds firmly, the pan is induction-compatible. If it slides off or doesn't attract at all, it won't work.
Does stainless steel work on induction?
Only some of it. Stainless with enough iron content is magnetic and induction-compatible; other stainless alloys aren't. Check the specific product rather than assuming all stainless steel qualifies.
Does cast iron work on induction?
Yes — cast iron is naturally magnetic and commonly cited as one of the best-performing materials on induction, both bare and enameled.
Can I use aluminum or copper pans on induction?
Not on their own — neither is magnetic. Many aluminum and copper pans are made induction-compatible by bonding a magnetic plate to the base, so check for that specifically.
Does ceramic cookware work on induction?
It depends on the base metal underneath the ceramic coating, not the coating itself — see our ceramic cookware guide for more on the coating side of that question.
Sourcing notes for this guide
In line with how we evaluate every guide (see our approach):
- Sourced: the electromagnetic-heating mechanism, the material compatibility findings, and the magnet-test method all reflect widely published cookware and appliance guidance gathered during this guide's research.
- Editorial analysis: the "where to start if you're shopping" section applies the sourced material compatibility findings to this site's own existing reviews.
- Not yet included: firsthand testing of any cookware on an induction cooktop. This guide does not claim otherwise.
- Still needs verification: the exact induction rating of any specific product before purchase — manufacturer specifications change, and this guide covers general material compatibility, not a guarantee for any one listing.
