Induction cooktops are becoming increasingly popular due to their energy efficiency, precise temperature control, and safety advantages. However, not all pans are compatible with induction cooking, which raises the question: what percentage of pans can be used on induction cooktops? The answer depends on the materials used in the pans. To be compatible with induction cooktops, pans must be made of ferromagnetic materials, such as cast iron, enameled steel, or magnetic stainless steel. Pans made of non-magnetic materials like ceramic, glass, non-magnetic copper, aluminum, or non-magnetic stainless steel will not work on induction cooktops. While there is no exact percentage available, it is clear that a significant proportion of pans can be used on induction cooktops, especially those made with ferromagnetic materials.
| Characteristics | Values |
|---|---|
| How induction cooktops work | Induction cooktops generate heat through electromagnetic energy |
| Pans compatible with induction cooktops | Pans made of ferromagnetic metal, such as cast iron, enameled steel, or stainless steel with a magnetic bottom |
| Pans incompatible with induction cooktops | Pans made of non-magnetic materials such as ceramic, glass, aluminum, or non-magnetic copper or stainless steel |
| Testing pan compatibility | Hold a magnet to the bottom of the pan; if it sticks, the pan is compatible |
| Symbols indicating compatibility | A stamped coiled spring symbol on the bottom of the pan or a symbol on the packaging |
| Benefits of induction cooktops | More energy-efficient, faster heating, safer, and more responsive to temperature changes |
| Drawbacks of induction cooktops | Requires special pans, higher installation cost |

What You'll Learn
Pans with a magnetic base
Induction cooktops use electromagnetic fields to generate instant heat directly to the cookware's bottom. Because of this technology, only certain materials will work on an induction cooktop. The most important consideration for cooking with an induction cooktop is owning cookware made of ferromagnetic metal, such as cast iron or some types of stainless steel.
To check if your cookware is compatible with an induction cooktop, try holding a magnet to the bottom. If the magnet clings to the underside, the cookware will work. If the magnet grabs the pan softly, you may not have good success with it on your cooktop. If there is no pull on the magnet, it doesn't contain the right metals and will not generate heat.
Many manufacturers have started putting an induction compatible symbol on the bottom of their cookware or noting compatibility on the packaging. The symbol often looks like a horizontal zig-zag or a coil. If you have an induction cooktop and a favourite piece of cookware that is not compatible, you might still be able to use a product like a stainless steel induction hob heat diffuser, which can be placed on the cooktop under the pan.
You can also purchase cookware with a magnetic base. For example, Wayfair offers a KitchenAid Stainless Steel 10-Piece Cookware Set, which is compatible with induction cooktops. Each pot in the set has a brushed interior, a polished mirror exterior, and a magnetized impact-bonded base for unrivaled heat conductivity, distribution, and retention.

Stainless steel pans
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 is why induction cooktops are more energy-efficient than gas or electric cooktops, as the cooking surface stays cool and they are more responsive to changes in temperature control.
It is important to note that some 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 have an induction cooktop and a favourite piece of cookware that is not induction-compatible, you can use a product like a stainless steel induction hob heat diffuser, which can be placed on the cooktop under the pan.

Cast iron pans
Induction cooktops are rising in popularity due to their energy efficiency, quick heating, and safer cooking surface. However, only certain types of pans can be used on induction cooktops.
While cast iron pans are compatible with induction cooktops, there are some considerations to keep in mind. Cast iron pans have a rough bottom surface and are heavier than other pans. This can lead to scratches or cracks on the cooktop if the pan is slid or dropped. To prevent damage, lift the pan when moving it, and always gently place it on the cooktop surface. Enameled cast iron pans can also be used, as the smooth enamel coating reduces the chance of scratching the cooktop.
Additionally, induction cooktops can heat pans very quickly and may cause hot spots. This can lead to internal stress in the pan, potentially resulting in cracks if there are defects in the metal. To mitigate this, avoid heating the pan too fast or too hot, and ensure the pan is clean and dry before use.

Pans with a flat bottom
Induction cooktops use electromagnetic fields to generate heat, so only certain materials will work on them. The best pans for induction cooktops are those with flat bottoms made from magnetic stainless steel, cast iron, enameled iron, or nickel.
To check if your current pans will work on an induction cooktop, try the magnet test. Simply hold a magnet to the bottom of the pan. If the magnet clings to the underside, the pan will work on an induction cooktop. If the magnet grabs the pan weakly, it may not work well. If there is no pull, the pan will not work on an induction cooktop.
You can also try the ruler test. Place the edge of a ruler across the bottom of the pan and hold it up to the light. If no light comes through, the pan is flat enough for an induction cooktop.
If you're buying new pans, check the packaging. Most manufacturers will state whether their products are induction-compatible. You can also look for the induction-compatible symbol, which often looks like a horizontal zig-zag or a coil.
Flat-bottomed pans made from magnetic stainless steel, cast iron, enameled iron, or nickel will work best on induction cooktops. These materials are ferromagnetic, meaning they will generate heat when used with an induction cooktop. Stainless steel skillets and cookware sets with cladded or disk bottoms are good options, as they tend to cook more evenly on induction than other styles. Heavy-bottomed pans are also a good choice, as they heat up quickly and evenly.

Non-stick pans
Induction cooktops use electromagnetic fields to generate heat directly to the cookware's bottom. Therefore, only certain cooking materials are compatible with induction cooktops. The most important consideration when using an induction cooktop is to use cookware made of ferromagnetic metal, such as cast iron or some types of stainless steel.
To check if a non-stick pan is compatible with an induction cooktop, you can look for an "induction compatible" symbol on the packaging or the bottom of the pan. This symbol often looks like a coil of wire with four loops. Alternatively, you can use the "magnet test" by placing a magnet against the bottom of the pan. If the magnet sticks, the pan will work on an induction cooktop.
It is worth noting that some manufacturers have started adding a magnetic layer to non-stick pans to make them compatible with induction cooktops. However, older non-magnetic pans will not work. Additionally, some copper pans are clad with magnetic metals, making them compatible with induction cooktops. Therefore, it is always worth testing non-stick pans with a magnet to determine their compatibility.

Frequently asked questions
Check if the base of the pan is attracted to a magnet. If the magnet sticks to the bottom of the pan, it is ferromagnetic and can be used for induction cooking.
Pans made of cast iron, enameled steel, or magnetic stainless steel are induction-compatible.
