Induction cooktops heat cookware directly using a magnetic field — which means your pots and pans need to be magnetic too, or they simply won't heat. Here's what to know before you switch, and how to avoid buying the wrong thing.

The magnet test

The simplest compatibility check: hold a standard fridge magnet to the base of your pan. If it sticks firmly, the pan will work on induction. If it doesn't stick at all, or only sticks weakly, it either won't heat or will heat very inefficiently.

Materials that work

• Cast iron — excellent heat retention, naturally and strongly magnetic, a genuinely great induction performer despite its age as a material.
• Magnetic-grade stainless steel — most quality cookware brands sold in Australia are induction-ready; check the base for an induction symbol or "suitable for induction" labelling if unsure.
• Enamelled cast iron — great for slow cooking and stews, carries cast iron's magnetic base under the enamel coating.
• Induction-clad multi-ply cookware — has a magnetic base layer bonded to aluminium or copper for even heat spread across the pan, combining fast heating with induction compatibility.

Materials that don't work (without an adapter)

• Pure aluminium
• Copper, unless it has a bonded induction-compatible base layer
• Glass and most ceramic cookware
• Some grades of "18/10" stainless steel that use a low-nickel, non-magnetic alloy

If you love your existing cookware and don't want to replace it, an induction interface disc/adapter plate is a low-cost workaround — though it adds a heat-transfer step that noticeably slows response time and reduces efficiency, so it's a compromise rather than a real fix.

Flat, correctly-sized bases matter more than you'd think

Induction zones sense the size of your pan's base to determine how much power to deliver to that area. Warped or undersized bases heat unevenly, and some cooktops won't register a pan at all if the base is too small relative to the zone. Buy pans matched reasonably closely to your cooktop's zone diameters for best results — check the specs on our comparison table for zone sizes across popular models, or see our dedicated pan-to-zone sizing guide.

Bottom line

Budget for a cookware refresh when switching to induction if your current set is aluminium or copper-based without an induction layer. A good stainless steel or cast iron set, chosen once with induction in mind, will comfortably outlast several cooktops.

Why some stainless steel fails the magnet test

"Stainless steel" covers a family of alloys, and only some of them are magnetic. The distinction comes down to the crystal structure: ferritic and martensitic stainless (the 400-series, including the 430 grade often used for induction-ready base plates) is magnetic and works. Austenitic stainless — the 300-series, including the very common 18/10 and 18/8 grades prized for corrosion resistance — is not magnetic in its normal state and will not heat on induction by itself.

This is why quality cookware is often built as a sandwich: an 18/10 stainless cooking surface for food contact and cleaning, an aluminium core for even heat spreading, and a magnetic 400-series stainless disc bonded to the bottom so induction can couple to it. A pan marked "18/10" may or may not work depending on whether it has that bonded base — which is exactly why the magnet test beats reading the label.

One practical wrinkle: heavily cold-worked austenitic stainless can become slightly magnetic at the edges or base from the forming process, enough to tug at a magnet weakly but not enough to cook properly. If the magnet only just clings rather than snapping on firmly, treat the pan as borderline — it may be detected intermittently or heat poorly and unevenly.

How each material actually behaves on induction

Warped bases: the problem people blame on the cooktop

Induction is less forgiving of a warped pan than gas or radiant electric, and it's a common source of "my new cooktop isn't working properly" complaints that turn out to be the cookware. Because the magnetic field weakens quickly with distance, a base that bows upward in the middle sits further from the coil exactly where you want the most coupling. The result is a ring of heat around the outside of the pan, a cool centre, and sometimes intermittent pan detection as the cooktop loses and regains contact.

Test it in ten seconds: put the pan on a flat benchtop and press one edge. If it rocks or spins, the base isn't flat. You can also lay a ruler across the base and look for light underneath. Thin pans warp from thermal shock — usually from being heated empty or rinsed under cold water while hot — so the fix is as much about habit as about hardware. Heavier-gauge bases warp far less, which is a real argument for buying fewer, better pans rather than a large cheap set.

Matching pan size to zone size

Induction heats the area of the pan sitting over the coil, not the whole pan. Put a 14cm milk pot on a 21cm zone and most of the coil has nothing to couple to; put a 28cm frypan on a 16cm zone and the outer third of the pan only gets heat that conducts sideways through the metal. Neither is dangerous, but both cook unevenly and waste energy.

As a rule of thumb, aim for a pan base within roughly 20% of the zone diameter, and note that most cooktops won't detect a base smaller than about 110–120mm at all. Cast iron and thick clad pans tolerate mismatch better than thin pans because they conduct heat sideways more effectively — which is why a heavy-based pan can feel more "even" on induction even when the zone is undersized. Our pan size and zone guide goes deeper on matching an existing collection to a zone layout.

What to buy if you're starting over

You don't need a matched set. A small, deliberate collection covers almost all home cooking on induction:

• One heavy clad stainless saucepan (18–20cm) — everyday sauces, grains, reheating.
• One large clad stainless pot (24cm+) — pasta, stock, batch cooking.
• One cast iron or carbon steel frypan (24–28cm) — searing, where induction's power genuinely shines.
• One non-stick frypan with a bonded magnetic base — eggs and fish, replaced every few years as non-stick wears.
• A flat-based carbon steel wok if you stir-fry often — see our induction wok guide, since round-bottomed woks don't work without a dedicated wok zone.

Check each piece's base diameter against your cooktop's zone sizes before buying, and prioritise base thickness over brand. Browse induction cookware sets on Amazon AU if you'd rather buy in one go.

Caring for cookware so it stays induction-friendly

Two habits protect both your pans and your cooktop glass. First, never heat an empty thin-based pan at high power — induction gets metal hot fast enough to warp a light base in seconds, and a warped base then cooks badly forever. Second, keep pan bases clean: burnt-on residue on the underside both insulates the pan from the glass and grinds into the surface every time you move it. Wipe the base as well as the inside, and lift pans rather than sliding them, which is the single biggest cause of the fine scratching covered in our cleaning guide.

Frequently asked questions

Will induction scratch my existing pans?

No more than any other flat cooktop surface — the usual precautions apply: lift rather than drag heavy cookware, and check pan bases occasionally for grit that could mark the glass.

Do I need to buy an entirely new cookware set?

Rarely all of it — most households already own at least some induction-compatible stainless steel or cast iron pieces and only need to replace the non-magnetic outliers.

Are induction interface discs worth buying instead of new cookware?

Only as a stopgap or for occasional use of one prized non-magnetic pan — for regular cooking, dedicated induction-compatible cookware performs noticeably better.

Why does my pan buzz or hum on induction?

A buzz or hum usually comes from the layers of a multi-ply pan vibrating slightly against each other in the alternating magnetic field. It is most noticeable at high power and with lighter clad pans, and it is not a fault in either the pan or the cooktop. Heavier, thicker-based cookware vibrates less and runs noticeably quieter.

Does more expensive cookware perform better on induction?

Up to a point. What matters is base thickness, flatness and how well the magnetic layer is bonded — and those do improve with price up to the mid-range. Past that you are mostly paying for handles, finish and brand. A heavy mid-range clad pan will outperform a thin premium-branded one on induction every time.

Can I use a round-bottom wok on an induction cooktop?

Not on a standard flat zone — there is too little contact for the cooktop to detect the wok or heat it evenly. You need either a flat-based wok or a cooktop with a dedicated concave wok zone. Wok rings do not solve this, because they lift the wok away from the glass and out of effective range of the coil.

How do I tell if a pan is induction-compatible before buying online?

Look for the induction symbol — usually a coil icon or four horizontal loops — in the product images or specification list, and check the base diameter against your zone sizes. Treat "suitable for all hob types" as a claim to verify rather than trust, and test with a magnet as soon as it arrives.
