What Cookware Works on Induction? The Magnet Test, Every Material, and Every All-Clad Line Checked

You just got an induction cooktop, or you are about to, and the question is simple: which of the pans you already own will work, and what should you buy for the rest? The answer comes down to one property of the metal touching the glass, and you can check it in ten seconds with a fridge magnet. This guide explains why, goes material by material (stainless, cast iron, carbon steel, nonstick, hard anodized, copper, aluminum, glass and ceramic), lists every All-Clad line with its compatibility from All-Clad's own chart, and covers the problems people hit even with "compatible" pans: a pan the hob will not detect, buzzing, hot centers and warped bases. Prices are Capital Cookware listings checked on October 25, 2026.

Why induction needs a magnetic pan

A gas burner or a radiant electric element makes heat and pushes it into the pan. Induction does not make heat in the cooktop at all. A copper coil under the glass carries a rapidly alternating current, which creates an alternating magnetic field just above the surface. When a pan with a magnetic (ferromagnetic) base sits in that field, the field drives electric currents around inside the metal of the base, and the metal's resistance turns those currents into heat. The pan becomes the burner. The US Department of Energy puts it in one line: "Any pots or pans with a flat bottom that a magnet sticks to will work with an induction cooktop" (energy.gov).

That is why the material matters so much. Iron and magnetic grades of stainless steel respond strongly to the field. Aluminum and copper conduct electricity far too well and are not magnetic, so the field passes through them without generating useful heat. Glass and ceramic do not conduct at all. It is also why induction is efficient: ENERGY STAR says about 85% of the heating energy reaches what is in the pan, compared with about a third for gas, and that boiling water can take nearly half the time (ENERGY STAR). The trade-off is that the pan has to cooperate.

The magnet test, done properly

Every cooktop maker and All-Clad itself recommend the same test, and it takes ten seconds. All-Clad's version: "place a magnet at the bottom of your pots or pans; if it sticks firmly, the cookware is induction-compatible" (All-Clad). A few details make it reliable:

• Use a real magnet, not a thin promotional fridge magnet. Weak flexible magnets can slide off pans that work fine. A small solid fridge magnet or a magnetic knife strip piece is better.
• Test the center of the base, not the side. Many pans are magnetic only on the bottom. A stainless pot can fail on its walls and pass on its base; the base is what counts.
• Test across the base. Some nonstick and copper pans have a steel disc or plate only in the middle. If the magnet sticks in the center but not near the edge, the pan will heat, but only over the plate, so a small plate on a big pan gives a hot center.
• "Sticks firmly" matters. A magnet that clings weakly and slides when you tilt the pan usually means a thin or weakly magnetic layer. Expect slow heating, error codes at low power or no detection on some hobs.
• Then check flatness. Set the pan on a flat counter. If it spins or rocks, it is warped and will heat unevenly or buzz on induction even if the magnet sticks (see why pans warp).

You can also look for a coil or spring-shaped induction symbol stamped on the base or printed on the box, or for wording such as "induction ready", "induction compatible" or "all cooktops including induction" on the listing. ENERGY STAR notes many induction-compatible pots carry an induction logo on the box (ENERGY STAR). Listings are worth reading closely: "all cooktops" sometimes means gas, electric and ceramic only.

What cookware works on induction, material by material

This is the whole answer in one table. "Base" is what touches the glass; that is the only part that has to be magnetic.

Two notes on that table. Cast iron and carbon steel work beautifully on induction, but Capital Cookware does not sell either, so we have no product to point to for them. And "stainless steel" alone does not answer the question: the grade of the outside layer decides it, which is why the magnet test beats the label.

Does stainless steel work on induction?

Most good stainless cookware does, but not because it is stainless. Stainless steel comes in magnetic and non-magnetic grades. The 18/10 stainless (type 304) used for most cooking surfaces is austenitic and barely magnetic. Ferritic grades such as 18/0 (type 430) are magnetic. Induction-ready clad cookware puts a magnetic stainless layer on the outside and keeps 18/10 on the inside for the cooking surface. All-Clad describes its D3, D5 and Copper Core lines as "bonded stainless steel construction with a magnetic stainless exterior" (All-Clad), and Capital's D3 2-quart listing says the same: "The magnetic stainless exterior works on gas, electric, ceramic and induction."

So an old stainless pot that fails the magnet test is usually 18/10 all the way through, or has a non-magnetic disc base. A pan that passes is fine, and clad stainless is one of the best things you can cook on with induction: the magnetic outer layer makes the heat, and the aluminum or copper core spreads it sideways so the whole base is hot, not just the circle over the coil. For more on choosing between tri-ply and 5-ply for this, see tri-ply vs 5-ply and the stainless steel buying guide.

Does nonstick or hard anodized cookware work on induction?

Only if it has a magnetic plate on the base. Hard anodized nonstick is aluminum underneath, and aluminum does nothing on induction by itself. Makers solve that by bonding a stainless steel plate to the bottom. Capital's HA1 listings describe it exactly: a "stainless steel, induction-bonded base" that "prevents warping, protects stovetops from scratching and ensures compatibility with induction ranges". Look at the bottom of the pan: a shiny steel disc on a dark anodized body is the giveaway. A plain dark bottom means aluminum only.

This is where the All-Clad nonstick family splits. All-Clad's own comparison chart lists Essentials Nonstick as not induction compatible, and HA1 Expert, NS Pro, HA1 Ceramic and NS Pro Ceramic as induction compatible (All-Clad chart). All-Clad also notes that square NS Pro shapes do not have the stainless base and are not induction compatible (All-Clad). The clad nonstick pans (D3, D5 and Copper Core with a nonstick interior) are induction compatible because the stainless body is. For a full line-by-line look at the coated pans, see All-Clad nonstick lines compared.

Does copper or aluminum cookware work on induction?

Not on its own. Copper and aluminum are the two best heat-spreading metals in cookware, and neither is magnetic. Solid copper pans, copper-exterior pans and plain aluminum pans (including most aluminum sheet pans and cheap aluminum pots) will not be detected. There are three ways around it:

• Buy copper or aluminum sealed inside magnetic stainless. All-Clad Copper Core and D3/D5 put the conductive metal in the middle of a stainless sandwich, so you get the heat spreading and induction compatibility. The Copper Core 4-qt sauce pan was $269.99 on Nov 11 and is listed as induction compatible.
• Buy a copper or aluminum pan with a steel base plate. Some makers bond a magnetic plate to the bottom. The magnet test tells you instantly.
• Use an interface disc. A flat steel plate that sits on the hob and heats like an ordinary hot plate. It works, but it gives up most of the speed and control of induction. We explain the trade-offs in the best induction cookware.

Capital's All-Clad C2 copper gratin, for example, has a copper exterior and its listing does not mention induction, so treat it as an oven dish on an induction kitchen unless the magnet says otherwise.

Which All-Clad lines work on induction?

This is the question we get most, so here is every line Capital Cookware carries, with All-Clad's chart and the Capital listing wording side by side. Prices are the lowest in-stock listing on October 25, 2026.

The pattern is easy to remember: anything All-Clad sells as bonded stainless works; nonstick works when it has the steel base; Essentials does not. Mixed lines such as B1 and Lagostina Nera vary piece by piece, so read the listing or test with a magnet. If you are shopping specifically for an induction kitchen, the D3 5-piece set ($379.99) and the HA1 10-piece set ($374.99) are both fully compatible; our induction picks go piece by piece.

My pan passed the magnet test but still does not work well

Compatibility is a yes or no; good performance is not. These are the usual problems, and what causes them.

Most cooktops also have a minimum pan size per zone, usually printed in the manual, and will not detect a pan whose magnetic base is much smaller than the marked circle. A big pan on a small zone works but only heats the middle, which is where a thick, conductive base helps most. Our Heat Lab shows this visually: a small burner under a thin pan makes a hot spot; the same burner under a clad pan spreads evenly.

Will induction damage my pans, or my pans damage the cooktop?

Induction is not harder on pans than gas, but it is faster, and that exposes bad habits. Heating an empty pan on the boost setting can push a thin pan past its limits in seconds; that is the classic cause of warped bases and, with nonstick, overheated coatings (see is nonstick cookware safe?). Start on medium, add fat early, and use boost only for boiling water.

The glass surface is the more delicate part. All-Clad's tips for stainless on induction include preheating gradually, avoiding sudden temperature changes and making sure pan bottoms are "clean, dry" to avoid scratching (All-Clad). Heavy cast iron is the biggest scratch risk because of its rough base; smooth clad stainless and the stainless plates on HA1 pans are kind to glass. Do not slide pans across the surface, and wipe spills once the zone cools.

How to switch to induction without replacing everything

You probably do not need a new set. Work through your cupboard in this order:

• Magnet-test everything. Cast iron, most clad stainless and any nonstick with a steel plate will pass. Put the passes in one cupboard.
• Check the passes for flatness. A rocking pan works poorly on induction even if it worked on gas.
• Replace the pans you use daily first. For most people that is a 10" or 12" frying pan, a 3-quart saucepan and a nonstick pan for eggs. A D3 10" fry pan ($69.99), a D3 2-qt sauce pan ($119.99) and an HA1 Expert 10" nonstick ($49.99) cover that for about $240.
• Then the big pot. Pasta and stock pots are where induction speed shines. The D5 8-qt stock pot with lid ($169.99) is listed "optimized for induction"; the HA1 8-qt stock pot ($69.99) is the budget option.
• Keep the rest for the oven. Glass baking dishes, ceramic and aluminum sheet pans still work in the oven; they just cannot go on the hob.
• Consider a set only if most of your pans fail. Count pans you will use, not pieces, as we explain in best cookware sets, or build only what you need with the custom set builder.

Induction-compatible picks by need (October 2026)

If you need to buy, these are in stock and listed as induction compatible on Capital Cookware as of October 25, 2026. Our best induction cookware guide explains each choice in depth.

Common mistakes

• Trusting "stainless steel" on the label instead of testing the base with a magnet.
• Testing the side of a pot instead of the bottom.
• Buying a nonstick set without checking for a steel base plate (All-Clad Essentials is not induction compatible).
• Using a 12" pan on the smallest zone and wondering why only the middle cooks.
• Preheating an empty pan on boost, which warps thin pans and overheats nonstick.
• Keeping a warped pan that rocks; on glass and induction it never heats evenly.

Key takeaways

• Induction heats the pan itself, so the base must be magnetic and flat.
• The magnet test on the center of the base is the fastest, most reliable check.
• Cast iron, carbon steel, enameled steel and clad stainless with a magnetic exterior all work.
• Aluminum, copper, glass and ceramic do not, unless a steel plate is bonded to the base.
• All-Clad D3, D5, Copper Core, HA1, NS1 and round NS Pro work; Essentials does not.

Verdict

Before you buy anything for a new induction cooktop, spend two minutes with a magnet: you will probably keep more pans than you expect. Replace the ones you use daily first, and favor clad stainless for even heat and nonstick with a steel base for eggs.
