Induction cooktops have become increasingly popular due to their quick heating, energy efficiency, and safety. However, a common question arises: do you need special pans for these cooktops? The short answer is yes. Induction cookers require ferromagnetic cookware, such as cast iron and some stainless steel. The pans must also have a flat bottom to ensure even heating and prevent vibration. While induction cooking is gentle on cookware, it's important to ensure your pans have magnetic properties. You can easily test this by holding a magnet to the bottom of the pan; if it sticks, it will work on an induction cooktop.

What You'll Learn
Pans with a magnetic base
Induction stove tops require pans with a magnetic base. This is because induction cooktops use copper coils to generate heat from electric currents directly to your cookware. Therefore, for an induction cooktop to work, pots and pans need to have a magnetic bottom.
You can determine whether your pans have a magnetic base by holding a magnet to the bottom of the pan to see if it sticks. If the magnet clings to the underside, the cookware will work on an induction cooktop. 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.
Some types of pans that have a magnetic base include stainless steel, cast iron, and porcelain enamel on metal. However, not all stainless steel pans are magnetic, so it is important to perform the magnet test to be sure. Cast iron is a slow heat conductor that retains heat very well, allowing for even cooking once the cooking temperature is reached. Porcelain enamel cookware will work on an induction cooktop as long as the base material of the cookware is magnetic metal.
When shopping for induction cookware, look for "induction-ready cookware" or "induction cooktop cookware." Additionally, ensure that the pans have a flat base that connects to the induction hob's cooking zone. An uneven bottom can vibrate and make noise on the glass surface, and it won't heat uniformly.

Stainless steel pans
Induction stove tops require ferromagnetic cookware, such as cast iron or some types of stainless steel. Stainless steel is often made with a variety of metals, and a high nickel content will block the magnetic field. Therefore, it is important to check if your stainless steel pans are compatible with an induction stove top.
To test if your stainless steel pans are compatible, simply hold a magnet to the bottom of the pan. If the magnet clings to the underside, the pan will work on an induction stove top. Some stainless steel pans may have a stamped coiled spring symbol on the bottom, indicating induction compatibility.
It is worth noting that not all stainless steel pans are magnetic, and those without magnetic bottoms will not work on induction stove tops. However, many manufacturers have started adding a magnetic layer to the bottom of pans, so newer stainless steel pans are more likely to be compatible.
If you have non-magnetic stainless steel pans that you wish to use on an induction stove top, you can use metallic discs sold for this purpose. However, this will reduce the performance of the stove.

Cast iron pans
Induction cooktops use electromagnetic energy to generate heat. This means that, for a pan to be compatible with an induction stove, it must contain ferromagnetic materials, such as iron. Cast iron pans are made of iron and therefore contain ferromagnetic properties, making them compatible with induction stovetops.
To check if a pan is compatible with an induction stove, you can hold a magnet to the bottom of the pan. If the magnet clings to the underside, the cookware will work on an induction stove. Cast iron pans will pass this test, as they are made of iron and are attracted to magnets.
It is also important to note that cast iron pans can be prone to thermal shock when used on induction cooktops. This is because the magnetic fields on induction cooktops are incredibly efficient, and if a cast iron pan is heated too quickly, the temperature of the iron can become imbalanced, causing thermal shock, which may cause the cookware to break. To avoid this, cast iron pans used on induction stoves should be preheated slowly with oil.

Glass, copper, and aluminium pans
Induction cooktops require magnetic pans or pan materials because the cooktop itself doesn't generate heat—the pan does. Copper, aluminium, and glass pans are not magnetic on their own, so they won't work on an induction cooktop unless they have a layer on the bottom with magnetic properties.
Some manufacturers have started adding a magnetic layer to the bottom of copper, aluminium, and glass pans, making them compatible with induction cooktops. To determine if your pan is compatible, hold a magnet to the bottom. If the magnet clings to the underside, the cookware will work on an induction cooktop. If there is no pull on the magnet, the pan won't work. Manufacturers often indicate compatibility by putting an "induction compatible" symbol on the bottom of their cookware or noting it on the packaging. The symbol often looks like a horizontal zig-zag or a coil.
If you have a favourite copper, aluminium, or glass pan that isn't compatible, you can use it with a converter disc placed under the pan, directly on the induction cooktop. You can also use a stainless steel induction hob heat diffuser.
There are copper pans on the market that are compatible with induction cooktops. For example, the De Buyer Prima Matera copper frying pan and the Netherton Foundry copper frying pan can be used on induction hobs.

Flat-bottomed pans
When it comes to induction stove tops, you need to use pans with magnetic properties. This is because induction stove tops have a copper coil positioned below the ceramic glass that generates heat directly to the cookware. As such, flat-bottomed pans are ideal for induction stove tops. Here are some things to consider when using flat-bottomed pans on an induction stove top:
Material
Magnet Test
If you're unsure whether your flat-bottomed pan is magnetic, a simple way to test it is by holding a magnet to the bottom of the pan. If the magnet sticks firmly, your pan is induction-compatible.
Size
It is important to match the size of the pan's base to the induction cooking zone. Using a pan with a smaller bottom diameter than the hob creates a weaker magnetic field and less heat output.
Maintenance
Induction stove tops are easy to clean and maintain. The surface stays relatively cool, and you can start cleaning just minutes after you're done cooking. Applying a ceramic cooktop cleaning cream before using your induction stove top for the first time can help protect it from scratches.
Handles
Look for flat-bottomed pans with comfortable, sturdy, and heat-resistant handles that stay cool during cooking. Well-attached handles can also reduce noise caused by vibration at higher power settings.

Frequently asked questions
Yes, induction stove tops require magnetic pans or pans with a magnetic base. You can test if your pan is compatible by holding a magnet to the bottom of the pan to see if it sticks.
Pans made from glass (including Pyrex), copper, or aluminium are not compatible with induction stove tops. Pans made from non-magnetic stainless steel will also not work.
Pans made from cast iron, porcelain enamel, or stainless steel designed for induction cooktops are compatible with induction stove tops. Some copper and aluminium pans have a magnetized base that is specifically designed for induction cooktops.
Induction stove tops use copper coils to generate heat from electric currents and transfer the heat directly to the pan. This means that only pans with ferromagnetic bodies will work on induction stove tops.
