Induction pans are made of ferromagnetic metals, such as cast iron, carbon steel, or stainless steel. The key consideration for induction cooking is that the cookware must be made of ferromagnetic metal, which interacts with the electromagnetic field created by the induction cooktop to heat up the pan. While some non-ferromagnetic pans may have a magnetic layer added to the bottom, making them compatible with induction cooktops, these will not conduct heat as efficiently as pans made entirely of ferromagnetic metals.

Induction pans require ferromagnetic metals
Induction pans are made of ferromagnetic metals, which are compatible with the electromagnetic energy generated by induction cooktops. This means that the pans need to have a magnetic quality, which is usually derived from metals such as cast iron, carbon steel, or stainless steel. The presence of ferromagnetic metals in the cookware allows it to interact with the magnetic coils beneath the cooking surface of an induction stove, creating an electromagnetic field that heats up the pan.
To check if a pan is made of ferromagnetic metals, a simple test can be performed by holding a magnet to the bottom surface of the pan. If the magnet sticks firmly or is repelled, the pan is likely made of ferromagnetic materials and is compatible with induction cooking. This is because any interaction between the magnet and the pan indicates the presence of ferromagnetism.
It is important to note that not all types of stainless steel are magnetic, so it is recommended to perform the magnet test specifically for stainless steel cookware. Additionally, while aluminium and copper pans are not ferromagnetic, some manufacturers have started adding a magnetized base or a magnetic layer to the bottom of these pans, making them compatible with induction cooktops.
Cast iron pans, despite being ferromagnetic, have some drawbacks when used with induction cooktops. They are slow to heat up and cool down, making them unsuitable for cooking that requires rapid temperature changes. Cast iron is also heavy, which can be a consideration for some users.
In summary, induction pans require ferromagnetic metals to function effectively on induction cooktops. This property is commonly found in metals such as cast iron, carbon steel, and certain types of stainless steel. The interaction between the ferromagnetic pans and the electromagnetic field generated by the cooktop results in efficient and precise temperature control, making induction cooking a popular choice for many home cooks.

Stainless steel, cast iron, carbon steel are compatible
Induction cooktops work differently from traditional gas and electric cooktops. Instead of burners or electric-resistance elements that warm up, the heat is created by an electromagnetic coil beneath the glass top. This coil creates a magnetic field that transfers current directly to magnetic cookware, causing it to heat up. Therefore, induction-compatible cookware needs to be made of ferromagnetic metal.
Stainless steel, cast iron, and carbon steel are all compatible with induction cooktops. Stainless steel skillets, saucepans, sauté pans, and stockpots are all induction-friendly. Some stainless steel products will not work on induction cooktops because they do not have enough ferromagnetic material. However, most food-grade stainless steel pans are induction-compatible.
Cast iron is ferromagnetic and compatible with induction. Cast iron skillets, Dutch ovens, and frying pans can be used on induction cooktops. Cast iron requires special care as it must be washed, dried, and reseasoned carefully to prevent rust. Enameled cast iron is also compatible with induction and is easier to clean than traditional cast iron.
Carbon steel is a good choice for induction cooktops. It is lighter than cast iron and easier to handle. Carbon steel skillets and frying pans can be used on induction. They are similar to cast iron but are thinner, lighter, and more responsive to changes in temperature. Carbon steel pans need to be seasoned to realize their natural non-stick capabilities.

Pans with pasted-on induction bottoms are not recommended
Induction cooktops use electromagnetic energy to generate heat, so the cookware used on them must be made of ferromagnetic metals. Cast iron, carbon steel, and some types of stainless steel are all ferromagnetic metals that can be used for induction cooking. Pans made of non-ferromagnetic materials like copper and aluminium are not induction-compatible, but some manufacturers have started adding a magnetic layer to the bottom of these pans.
However, pans with pasted-on induction bottoms are not recommended. While this modification technically makes the pan induction-compatible, it also means that the induction compatibility is isolated to the centre of the pan, rather than extending to the sides. This can result in uneven cooking, with food remaining uncooked off to the side.
Instead, it is recommended to invest in high-quality, induction-compatible cookware that is designed with a completely magnetic build. For example, 5-ply stainless clad pans are not only induction-compatible but also optimized for induction cooking. These pans are designed with a layer of stainless steel and aluminium on the bottom, known as tri-ply or clad, which maximizes the even distribution of heat to all parts of the pan.
When shopping for induction cookware, it is important to look for high-quality, durable options that will provide even heating. Stainless steel induction pans with aluminium or copper cores placed between the interior and exterior layers of steel can conduct heat more effectively than stainless steel alone. Additionally, cast iron pots and pans are compatible with induction cooktops and are known for their non-stick cooking capabilities when seasoned properly. However, cast iron is slow to heat and cool and can be heavy, so it may not be the best option for all cooks.
To test if your existing cookware is induction-compatible, simply hold a magnet to the bottom of the pan. If the magnet sticks firmly, your pan is induction-compatible.

Non-magnetic pans won't work
Induction cooktops use electromagnetic energy to generate heat from electric currents directly to your cookware. This means that the cookware you use needs to be made of ferromagnetic metal. Materials such as cast iron, carbon steel, and some types of stainless steel are ferromagnetic and therefore compatible with induction cooktops.
Non-ferromagnetic materials such as copper and aluminium are not induction-compatible. Glass cookware will also not work with induction cooktops. This is because these materials are not attracted to magnets and therefore cannot generate heat through electromagnetic energy.
While some manufacturers have started adding a magnetic layer to the bottom of non-magnetic pans, older, non-magnetic pans will not work. This is because the induction compatibility is isolated to the bottom of the pan, meaning any food being cooked off to the side will remain uncooked.
To test whether your cookware is induction-compatible, simply hold a magnet to the bottom surface. If the magnet sticks, your cookware is induction-compatible. If there is no pull on the magnet, your cookware does not contain the right metals to generate heat and will not work on an induction cooktop.

Pans with a magnetized base are designed for induction
Induction cooktops work by creating a magnetic field between the pot and the magnetic coils beneath the cooking surface. This means that the cookware you use needs to be made of ferromagnetic materials, such as cast iron, carbon steel, or stainless steel. Pans made of non-ferromagnetic materials like copper, aluminium, or glass will not work on an induction hob unless they have a magnetized base.
Some manufacturers have started adding a magnetized base or a magnetic layer to the bottom of pans made with non-ferromagnetic materials. These pans are specifically designed for use on induction cooktops. The magnetized base allows the pan to interact with the electromagnetic field generated by the induction cooktop, thus heating the pan.
When shopping for induction cookware, you can check if your pan is compatible by performing a magnet test. Simply hold a magnet to the bottom of the pan and see if it sticks. If the magnet sticks, the pan is ferromagnetic and can be used for induction cooking.
It is important to note that not all stainless steel pans are magnetic, so it is always a good idea to perform the magnet test before purchasing or using a stainless steel pan on an induction cooktop. Additionally, while cast iron pans are compatible with induction cooktops, they are slow to heat up and cool down, and they are quite heavy.
