Induction cooking differs from conventional gas or electric cooking in that only certain types of pans are compatible with induction cooktops. Induction cooking uses direct electrical induction to heat cookware, meaning that the cookware must contain a ferromagnetic metal such as cast iron or certain types of stainless steel. Pans made from aluminium, copper, or glass will not work on an induction cooktop unless they have a layer on the bottom with magnetic properties. To test whether a pan is induction-compatible, simply hold a magnet to the bottom of the pan. If the magnet sticks, the pan will work on an induction cooktop.

Induction pans require ferromagnetic metals like cast iron or stainless steel
Induction cooking is a process that uses direct electrical induction to heat cookware, rather than relying on flames or heating elements. It is one of the most efficient ways of cooking, producing less waste heat and allowing for rapid changes in temperature. To work with induction, cookware must be made of ferromagnetic metal, such as cast iron or certain types of stainless steel. This is because induction cooking creates a magnetic field between the pot and the magnetic coils beneath the cooking surface, which then heats the contents of the pot.
Ferromagnetic metals are key to induction cooking because they can be heated by a magnetic field. Cast iron is a ferromagnetic metal and is therefore compatible with induction cooktops. Enameled cast iron is also compatible. Some types of stainless steel are also induction-compatible, but this is where it gets a little tricky. Stainless steel can be made with a variety of metals, and if it has a high nickel content, it will block the magnetic field and not work with induction.
To determine whether your stainless steel cookware will work with induction, you can perform a simple test. 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 only softly grabs the pan, it may not work well. If there is no pull on the magnet, the pan will not work with induction. Manufacturers have started putting an "induction compatible" symbol on their cookware or noting compatibility on the packaging, so be on the lookout for that as well.
If you have a favourite piece of cookware that is not induction-compatible, there are products like stainless steel induction hob heat diffusers that can be placed on the cooktop under the pan. This will then heat the contents of the pan. Additionally, many manufacturers have begun adding a magnetic layer to pans made of non-magnetic materials like aluminium, copper, or glass, so these newer pans may also be compatible with induction cooktops.

Check if a magnet sticks to the pan to see if it's induction-compatible
Induction cooking differs from conventional gas or electric cooking, and only specific types of pans work on an induction cooktop or burner. Induction cooking works 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.
To check if your cookware is induction-compatible, you can try the magnet test. Simply place a magnet on the base of your pan, and if it sticks firmly, it will work with your induction cooker. If the magnet does not stick firmly, it may still work, but it will not work efficiently. If the magnet does not stick at all, the pan does not have the right metals to create heat with an induction cooker. It is important to note that the magnet needs to adhere to the pan very well. If it slides off easily, the pan may not have enough magnetic qualities to work well on an induction stove.
Most pure metal pans, such as cast iron, steel, and some stainless steel, will work with induction stovetops. However, if other materials are blended in, or the pan is made of aluminum, glass, or ceramic, your food will not cook. Cast iron, enameled cast iron, and many types of stainless steel cookware are all induction-compatible. There are exceptions, though, as some stainless steel pans have a high nickel content that will block the magnetic field. Aluminum, copper, or glass cookware won't work unless they have a layer on the bottom with magnetic properties.
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.

Pans with aluminium or copper bases are unlikely to be induction-compatible
Induction cooking is a process that uses direct electrical induction to heat cookware, rather than relying on flames or heating elements. It is one of the most efficient ways of cooking, producing less waste heat and allowing for rapid changes in temperature. This is achieved through an oscillating magnetic field that induces an electrical current in the cookware, which is converted into heat by resistance.
For a pan to be compatible with an induction cooktop, it must contain a ferromagnetic metal such as cast iron or certain types of stainless steel. Pans made from aluminium or copper are unlikely to be induction-compatible. This is because the magnetic field cannot produce a concentrated current in these metals. Aluminium and copper require much higher frequencies to generate the heat necessary for cooking.
There is a simple test to determine if a pan is induction-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 cooktop. If there is no pull on the magnet, the pan will not work on an induction stove. It is worth noting that some non-stick aluminium pans may be lined with another magnetic metal, making them compatible despite being made of aluminium.
Manufacturers have become better at noting whether their products are induction-compatible. Many will include an "induction compatible" symbol on the bottom of their cookware or indicate compatibility on the packaging. This symbol often resembles a horizontal zig-zag or a coil.

Induction cooking uses direct electrical induction to heat the pan
Induction cooking is a process that uses direct electrical induction to heat the cookware. This is achieved through an oscillating magnetic field that induces an electrical current in the pan, which is converted into heat by resistance. The pan is placed on an induction stove, which usually has a heat-proof glass-ceramic surface above a coil of wire with an alternating electric current passing through it. This creates a magnetic field that heats the contents of the pan.
Induction cooking is more energy-efficient than traditional gas or electric stoves because it allows for high power and rapid increases in temperature, with instantaneous changes in heat settings. It also has safety advantages, as the cooktop itself remains relatively cool and there are no open flames or heating elements. The smooth surface of the cooktop also makes it easy to clean.
For a pan to work with induction cooking, it must contain a ferromagnetic metal such as cast iron or certain types of stainless steel. A simple way to check if a pan is compatible is to place a magnet on the bottom of the pan. If the magnet sticks, the pan will work on an induction cooktop. Manufacturers have also started adding an induction compatible symbol on the bottom of their cookware or noting compatibility on the packaging.
It's important to note that not all pans are compatible with induction cooking. Pans made of aluminium, copper, or glass may not work unless they have a magnetic layer on the bottom. Additionally, some stainless steel pans with high nickel content can block the magnetic field and may not be compatible.

Induction cooking is more energy-efficient than gas or electric cooktops
Induction cooktops are more energy-efficient than gas or electric cooktops. Induction cooktops are 84% energy efficient, while gas cooktops waste about 60% of the energy and electric cooktops waste 26% of the energy. Induction cooktops achieve this high energy efficiency because they heat the cookware directly using an electromagnetic field. This direct transfer of energy from the electromagnetic elements to the ferrous metal in pots and pans means there is no intermediary where energy losses can occur.
The electromagnetic field also provides more precise and even heating compared to traditional cooktops. This means that induction cooktops can boil water faster than gas and traditional electric cooktops. The faster cooking time also contributes to the energy efficiency of induction cooktops.
Another factor contributing to the energy efficiency of induction cooktops is the size of the burner. With gas and electric cooktops, if the burner is larger than the pot or pan, energy is wasted heating the area around the cookware. Induction cooktops, on the other hand, have elements that match the pan size, reducing energy waste.
The environmental benefits of induction cooking are also seen in the improved indoor air quality. Since the heat is generated from within the cookware itself, the cooktop does not get as hot as traditional gas or electric cooktops. This reduces the risk of burns and improves air quality by reducing the amount of heat released into the surrounding environment.
While induction cooktops offer energy efficiency and environmental benefits, there are some considerations to keep in mind. Firstly, switching to induction cooking can be expensive, and it can be costly to replace existing cookware with induction-compatible options. Additionally, induction cooktops may not be compatible with all types of cookware. Cast iron, enameled cast iron, and some types of stainless steel are induction-compatible, while aluminium, copper, and glass cookware may not work unless they have a magnetic layer on the bottom.
