Induction cooktops are unique in that they require ferromagnetic cookware, such as cast iron or stainless steel, to generate heat. This is because induction cooktops create a magnetic field between the pot and the magnetic coils beneath the surface, heating the contents of the pot directly. To determine if your cookware is induction-compatible, simply hold a magnet to the bottom of the pan; if it sticks, it will work on an induction cooktop. While induction pans are specifically designed for use on induction cooktops, some may be oven-safe, depending on the material and manufacturer's instructions.

Induction pans are made from ferromagnetic metals
Induction cooktops are rising in popularity due to their energy efficiency, quick heating, and safer cooking surface. However, they require specific types of pans, namely those made from ferromagnetic metals.
Ferromagnetic metals are essential for induction cooking because they can interact with the electromagnetic energy produced by the cooktop. This energy is generated by a copper coil located under the cooktop's surface, creating a magnetic field that heats the contents of the pan directly. As a result, the cooktop surface cools down quickly once the pan is removed.
So, what exactly are ferromagnetic metals, and why are they compatible with induction cooktops? Ferromagnetic metals are attracted to magnets and can become magnetized themselves. When a ferromagnetic pan is used on an induction cooktop, it channels the magnetic field lines efficiently, allowing for effective heating. Common ferromagnetic metals used for induction pans include cast iron, enameled cast iron, and certain types of stainless steel.
It's important to note that not all stainless steel is compatible with induction cooktops. Stainless steel with a high nickel content, for example, will block the magnetic field. Additionally, aluminum, copper, and glass cookware will not work unless they have a magnetic layer added to the bottom.
To determine if a pan is made from ferromagnetic metal and compatible with induction cooking, a simple test can be performed. Flip the pan over and hold a magnet to the bottom. If the magnet sticks, the pan is ferromagnetic and suitable for induction cooking. This test can be especially useful when shopping for new cookware or confirming the compatibility of existing pans.

Cast iron, enameled cast iron, and stainless steel are induction-compatible
Induction cooktops are unique in that they generate electromagnetic energy to cook food. This means that only ferromagnetic cookware will work on induction cooktops. Cast iron, enameled cast iron, and stainless steel are induction-compatible materials.
Cast iron is a durable and affordable option for induction cooking. It is heavy and hard to lift, but newer cast iron skillets are more ergonomic and easier to manage. Cast iron also becomes more seasoned over time, making it a great choice for those who want a pan that improves with age.
Enameled cast iron is another option for induction cooking. It is easier to clean than traditional cast iron but is more fragile and will never build up seasoning. Some popular options for enameled cast iron include the Le Creuset Dutch Oven and the Staub Grill Pan.
Stainless steel is a bit more complicated when it comes to induction compatibility. While many types of stainless steel cookware are induction-compatible, some are not due to the variety of metals used in their construction. Stainless steel with a high nickel content, for example, will block the magnetic field and not work on an induction cooktop. To test if a stainless steel pan is induction-compatible, simply hold a magnet to the bottom. If the magnet sticks, the pan is induction-compatible.
It is important to note that not all induction-compatible pans are oven-safe. Always check the manufacturer's care instructions to determine if your pan can be used in the oven and at what temperature.

Non-magnetic materials like glass, aluminium, and copper won't work
Induction cooktops are different from conventional gas or electric cooktops, and only certain types of pans are compatible with them. Induction cooktops generate electromagnetic energy, so you have to use ferromagnetic cookware to cook on them. Non-magnetic materials like glass, aluminium, and copper won't work on induction cooktops.
To test whether your cookware is compatible with an induction cooktop, simply hold a magnet to the bottom of the pan. If the magnet sticks, the pan is ferromagnetic and can be used for induction cooking. If the magnet doesn't stick, the pan won't work on an induction cooktop. This is because induction cooking creates a magnetic field between the pot and the magnetic coils beneath the cooking surface, and the energy created in this electromagnetic field heats the contents of the pot.
Glass, aluminium, and copper pans won't work on induction cooktops because they are not ferromagnetic. However, some copper pans are now being made with a layer of magnetic metal on the bottom, making them compatible with induction cooktops. Additionally, you can use a product like a stainless steel induction hob heat diffuser, which can be placed on the cooktop under the pan, transferring heat to the pan's contents.
It's worth noting that while some non-magnetic pans may not work on induction cooktops, they can still be used in ovens. Oven compatibility depends on the material and construction of the pan, and you should always check the manufacturer's care instructions before placing any pan in an oven.

Check the bottom of the pan for a stamped coiled spring symbol
Induction cooktops differ from conventional gas or electric cooking methods, and only certain types of pans can be used on them. Induction cooking involves 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 the cookware used for induction cooking must be made of ferromagnetic metal.
To check if your cookware is induction-compatible, you can use a magnet. Flip the pan over and hold the magnet to the bottom. If the magnet sticks to the bottom, the pan is ferromagnetic and can be used for induction cooking.
You can also check the bottom of the pan for a stamped coiled spring symbol. This symbol indicates that the cookware is induction-compatible. The symbol often looks like a horizontal zig-zag or a coil. Many manufacturers have started adding this symbol to their cookware to indicate compatibility.
If your cookware is not induction-compatible, you can still use it on an induction cooktop with the help of a heat diffuser. A stainless steel induction hob heat diffuser can be placed on the cooktop under the pan, allowing the contents of the pan to be heated.
It is important to note that not all pans are oven-safe. While some pans, like cast iron skillets, Dutch ovens, and stainless steel skillets, are oven-safe, others may only be safe to low temperatures. Always check the manufacturer's care instructions to determine if your pan can be used in the oven.

You can use a magnet to test if a pan is induction-compatible
Induction cooktops generate heat through electromagnetic energy, so you must use ferromagnetic cookware, such as cast iron, enameled steel, or stainless steel designed for induction cooking. Non-ferromagnetic cookware will not be detected by the burner and won't heat up. Non-magnetic cookware like ceramic, glass, non-magnetic copper, aluminium, and non-magnetic stainless steel won't work on induction cooktops.
To determine whether your cookware is compatible, you can use a simple trick: grab a magnet and place it against the bottom of the pan. If the magnet sticks, the pan will work on an induction appliance. If the magnet slides off easily, the pan may not have enough magnetic qualities to work on an induction stove. You can also check the bottom of your cookware for a stamped coiled spring symbol, which indicates induction compatibility.
Some non-stick pans have a cast iron, enameled steel, or magnetic stainless steel base that can react with the cooktop to generate heat. However, those with non-magnetic bases won't work. If you have a pan made of aluminium, glass, or ceramic, your food won't cook on an induction stove.
When shopping for new pots and pans, it's a good idea to bring a magnet with you to the store to test their compatibility with induction cooktops.
