Induction cooktops use a magnetic field to stimulate the atoms in a piece of cookware, causing friction and creating heat directly in the pot or pan. This requires a ferromagnetic metal, which pure copper is not. Therefore, copper pans are generally not compatible with induction cooktops. However, some copper pans have a layer on the bottom with magnetic properties, such as stainless steel, which makes them compatible with induction. One example is the Samuel Groves Induction Copper Chef Pan, which has a stainless steel base in addition to its copper exterior.

What You'll Learn
Copper chef pans are not magnetic
Induction cooktops use a magnetic field to stimulate the atoms in a piece of cookware, causing friction and generating heat directly in the pot or pan. This requires a ferromagnetic metal, i.e., a metal with magnetic properties. Copper chef pans are not magnetic, and neither is pure copper. Therefore, they typically cannot be used directly on induction hobs. Copper is paramagnetic and not ferromagnetic, so it cannot produce a concentrated magnetic current.
However, there is an exception to this rule. Copper pots or pans lined with stainless steel can sometimes work on induction stoves, as stainless steel is a ferromagnetic metal. It is important to note that this is not true for all stainless steel-lined copper cookware, and manufacturers' notes should be checked to ensure compatibility. A simple test to determine if cookware is compatible with induction stoves is to 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 cookware does not contain the right metals and will not generate heat.
Copper chef pans have superior temperature control and conductivity, making them a popular choice for serious cooks and pastry chefs. They are the best overall choice for searing, sautéing, and making delicate caramels, jams, and other sugar-based recipes. While copper chef pans may not be compatible with induction cooktops due to their non-magnetic properties, they are still an excellent option for gas or electric stove owners.
It is worth noting that some manufacturers have started adding a magnetic layer to the bottom of copper pans to make them compatible with induction cooktops. Additionally, there are ways to make non-compatible pans work on induction stoves, such as using a stainless steel induction hob heat diffuser.

Induction cooktops require magnetic fields to heat cookware
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 requires a ferromagnetic metal, i.e., a metal that has magnetic properties. Therefore, induction cooktops require cookware made of ferromagnetic metals.
Copper, unfortunately, is not one of them. While copper is an excellent material for cookware, heating efficiently and responding almost instantly to temperature changes, it is not magnetic and hence not compatible with induction cooktops. The same goes for aluminium and glass cookware.
However, there is an exception to this rule. Copper pots or pans lined with stainless steel can sometimes work on induction stoves. This is because stainless steel is ferromagnetic. But this is not true of all stainless steel-lined copper cookware, so it is important to check the manufacturer's notes to ensure compatibility.
There are a few ways to test if your cookware is compatible with induction cooktops. One way is to use a magnet to see if it attracts the underside of the cookware. If the magnet clings to the underside, the cookware will work on an induction cooktop. If there is no pull on the magnet, the cookware will not generate heat. Another way is to look for an ""induction compatible" symbol on the bottom of the cookware or note compatibility on the packaging. The symbol often looks like a horizontal zig-zag or a coil.

Copper is not ferromagnetic
Induction cooktops use a magnetic field to stimulate the atoms in a piece of cookware, causing friction which then creates heat directly in the pot or pan. This requires a ferromagnetic metal, i.e., a metal that has magnetic properties. Copper is not ferromagnetic and therefore is not compatible with induction cooktops. While copper is a fantastic heat conductor, it does not have the magnetic properties required for induction cooking.
Ferromagnetism is a property of certain materials, such as iron, that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to magnets, which is a consequence of their substantial magnetic permeability. Magnetic permeability describes the induced magnetization of a material due to the presence of an external magnetic field.
Copper does not have the required magnetic properties because it has a full 3d shell and therefore does not have an unpaired electron. To be ferromagnetic, a metal must have unpaired spins, which copper does not have. Copper is diamagnetic, meaning it is weakly repelled by magnets. When exposed to a strong magnetic field, copper can retain some magnetism even after the field is removed. However, this is not sufficient for induction cooking, which requires a strong and immediate magnetic response.
There is one exception to the rule that copper is not induction-compatible. Copper pots or pans lined with stainless steel can sometimes work on induction stoves. This is because stainless steel can be made with a variety of metals, some of which have magnetic properties. However, this is not true of all stainless steel-lined copper cookware, so it is important to check the manufacturer's notes to ensure compatibility.
In summary, copper is not ferromagnetic, and therefore most copper cookware is not compatible with induction cooktops. However, there are some exceptions, such as copper cookware lined with certain types of stainless steel.

Copper pans lined with stainless steel can work on induction stoves
Copper pans are as functional as they are beautiful, but they may not work on your stove. Induction cooktops use a magnetic field to stimulate the atoms in a piece of cookware, creating friction and generating heat directly in the cookware. This requires a ferromagnetic metal, such as iron, which is found in stainless steel, carbon steel, and cast iron.
Copper is not magnetic on its own, so typically, pure copper pans cannot be used directly on induction hobs. However, there is an exception to this rule: copper pans lined with stainless steel can sometimes work on induction stoves. This is because stainless steel is ferromagnetic and thus compatible with induction stoves.
Not all stainless steel-lined copper cookware is compatible with induction stoves, so it is important to check the manufacturer's notes to ensure compatibility. You can also test your copper cookware with a fridge magnet; if it attracts the magnet, it is ferromagnetic and potentially induction-compatible. If it repels or shows no interaction with the magnet, it is not suitable for induction cooking.
One example of a copper pan lined with stainless steel that is compatible with induction stoves is the Copper Coeur Line by Falk Culinair USA. This three-layer pan has a 0.2 mm stainless steel lining fused with a 1.9 mm copper core and a 0.4 mm ferritic stainless steel exterior, making it compatible with induction ranges.
In addition to copper pans lined with stainless steel, there are other alternatives available if you want to use copper cookware with your induction stove. For example, you can place a stainless steel induction hob heat diffuser on the cooktop under the pan, which will heat the contents of the pan.

Copper is the best heat conductor among cookware materials
Copper is widely recognised as one of the best conductors of heat among cookware materials. This is due to its extremely high thermal conductivity, which is twice that of aluminium, the leading cooking appliance metal. Copper's high thermal conductivity means that it will heat up and cool down very quickly, making it ideal for high-heat searing or gently simmering delicate sauces that require very specific cooking temperatures. Copper also spreads heat evenly across its surface, making it the material of choice for many pastry chefs who require even heat distribution and responsiveness for making delicate caramels, jams, and other sugar-based recipes.
However, copper's responsiveness to changes in temperature means that it is not suitable for all cooking scenarios. For example, when slow-cooking dishes such as stews or tenderising meat, it is better to use a material with a lower thermal conductivity such as enameled cast iron or ceramic. In these cases, the cookware's ability to retain heat for an extended period is more important than its ability to conduct heat efficiently.
Another factor to consider when choosing cookware is the potential for the metal to alter the taste of the food. None of the most popular metals for cookware, including copper, can conduct heat efficiently without impacting the flavour of the food. Therefore, it is important to select the right type of metal depending on the cooking technique.
In recent decades, aluminium has been the most popular choice among consumers, accounting for over 50% of all cookware sold. Aluminium is a good alternative to copper as it has high thermal conductivity and is lightweight, easy to manufacture, and more affordable. However, copper is still preferred for the bottoms of high-quality cookware due to its superior heat distribution.
In summary, copper is an excellent choice of material for cookware due to its high thermal conductivity, even heat distribution, and responsiveness to changes in temperature. However, other factors such as cooking technique, cost, and potential impact on food flavour may lead cooks to choose alternative materials such as aluminium or cast iron.
