Induction cooktops require ferromagnetic cookware, such as cast iron, enameled cast iron, and some types of stainless steel. Non-magnetic materials such as ceramic, glass, non-magnetic copper, aluminium, and non-magnetic stainless steel are incompatible with induction cooktops. To determine whether a pan is induction-compatible, a simple test involves placing a magnet against its bottom surface; if the magnet sticks, the pan can be used for induction cooking. Some manufacturers also indicate induction compatibility by stamping a coiled spring symbol at the bottom of the cookware.

Cast iron, enameled cast iron, and stainless steel are induction-compatible
Induction cooktops require certain types of metal pots and pans. The most important consideration when choosing cookware for an induction cooktop is to use cookware made of ferromagnetic metal, such as cast iron or some types of stainless steel. Cast iron is ferromagnetic (i.e., able to produce a magnetic field), so it will work on an induction cooktop. Enameled cast iron is also induction-compatible because it is still cast iron through and through, even with the enamel coating.
To test whether a pan is induction-compatible, you can use a simple trick: take a magnet and place it against the bottom of the pan. If the magnet sticks, the pan will work on an induction cooktop. If the magnet does not stick, the pan is not induction-compatible.
Some non-induction-compatible pans can be used on induction cooktops with a stainless steel induction hob heat diffuser placed under the pan. Additionally, some manufacturers sell metallic discs that can be placed under non-ferromagnetic pans to allow them to work on induction cooktops, although the performance of the stove may be reduced.
It is important to note that not all stainless steel pans will work on induction cooktops. Stainless steel comes in both magnetic and non-magnetic forms, and only magnetic stainless steel will work on induction. Aluminum pans will also not work on induction cooktops, as they have a lower electrical resistance and can damage the stove.

Non-magnetic materials like aluminium, copper, and glass won't work on induction cooktops
Induction cooktops work by creating a magnetic field between the pot and the magnetic coils beneath the cooking surface. The energy created in the electromagnetic field heats the contents of the pot. This means that non-magnetic materials like aluminium, copper, and glass won't work on induction cooktops.
Aluminium pans, for example, do not melt on induction cooktops, but using one can melt the stove. Aluminium and copper pans have lower electrical resistance, which dissipates the eddy currents faster and places a higher current draw on the stove. Some stoves are designed to heat aluminium pans, but this increases the cost of the stove by a significant amount. Other stoves are designed to disable when an aluminium pan is detected, which is a cheaper option and is included on all new stoves.
To test whether your pans are compatible with an induction cooktop, simply hold a magnet to the bottom of the pan. If the magnet sticks, the pan is compatible. If there is no pull on the magnet, the pan won't generate heat. Many manufacturers have started putting an "induction compatible" symbol on the bottom of their cookware or noting compatibility on the packaging. This symbol often looks like a horizontal zig-zag or a coil.
If you want to continue using non-magnetic pans, you can use metallic discs sold for this purpose. However, the performance of the stove will drop to levels comparable to old-style resistive stoves.

Check the bottom of the pan for a stamped coiled spring symbol to indicate induction compatibility
When it comes to using regular pans on induction cooktops, it's important to understand the underlying principle of induction cooking. Induction cooktops rely on electromagnetic fields to heat cookware directly. This means that the cookware must be made of ferromagnetic metal, such as cast iron or certain types of stainless steel, to interact with the electromagnetic energy generated by the cooktop.
Now, let's focus on the task at hand: checking the bottom of your pan for the stamped coiled spring symbol. This symbol is a quick and easy way to determine if your pan is induction-compatible. It indicates that the cookware has been designed and tested for use on induction cooktops. By finding this symbol, you can be confident that your pan will work effectively with the induction stove's electromagnetic fields.
The stamped coiled spring symbol is usually found on the base of the pan, often near the centre or around the edges. It may be embossed or engraved, so it could be slightly raised or recessed. The symbol itself resembles a coil of wire, similar to a tightly wound spring. Sometimes, this symbol is enclosed within a circle or another geometric shape.
If you find the stamped coiled spring symbol on the bottom of your pan, it confirms that the cookware is induction-compatible. This symbol is a reliable indicator that the pan has the necessary magnetic properties to interact with the electromagnetic fields generated by induction cooktops. With this knowledge, you can rest assured that your pan will heat up efficiently and evenly when used on an induction stove.

Non-induction pans can be used with metallic discs, but performance will drop
Induction cooktops require ferromagnetic cookware, such as cast iron or certain types of stainless steel. Non-magnetic materials such as ceramic, glass, non-magnetic copper, aluminium, and non-magnetic stainless steel will not work on induction cooktops.
If you have a non-induction pan, you can use it on an induction cooktop with a metallic disc, which is sold for this purpose. However, the performance of the stove will drop to levels comparable to old-style resistive stoves.
You can test whether your pan is compatible with an induction cooktop by placing a magnet on its bottom. If the magnet sticks, the pan is compatible. If not, the cooktop may flash an error code or indicator light.
It is worth noting that some non-stick pans are induction-compatible. For example, Caraway pans have a ceramic coating wrapped around an aluminium body, but a steel base makes them induction-compatible.

Some non-stick pans are induction-compatible, but it depends on the pan's magnetism
Induction cooktops require ferromagnetic cookware, such as cast iron or some types of stainless steel, to function. This is because induction cooktops generate heat through electromagnetic energy, which requires a magnetic field between the pot and the cooktop.
Non-magnetic materials like ceramic, glass, non-magnetic copper, aluminium, and non-magnetic stainless steel are not compatible with induction cooktops. However, some non-stick pans may be induction-compatible if they have a magnetic metal layer. For example, Caraway pans have a ceramic coating and an aluminium body but include a steel base that makes them induction-compatible.
To determine if a pan is induction-compatible, a simple test with a magnet can be performed. By placing a magnet against the bottom of the pan, you can see if it sticks. If the magnet sticks, the pan is ferromagnetic and compatible with induction cooktops. If there is no attraction between the magnet and the pan, it indicates that the pan does not contain the necessary metals for induction cooking.
Manufacturers have also made it easier for consumers to identify induction-compatible cookware. Many manufacturers now include an ""induction-compatible" symbol on the bottom of their cookware or note compatibility on the packaging. This symbol often resembles a horizontal zig-zag or a coil. Therefore, it is advisable to look for this symbol when purchasing cookware for an induction cooktop.

Induction cooking uses electromagnetic energy to create a magnetic field between the pot and the magnetic coils beneath the cooking surface. This field heats up the contents of the pot.
Pans made of ferromagnetic metal, such as cast iron, enameled cast iron, and some types of stainless steel, are compatible with induction cooktops.
A simple way to check is to hold a magnet to the bottom of the pan. If the magnet sticks, the pan is induction-compatible.
