What is an Induction Stove?

Everything you need to know about induction stoves, what cookware works for them, and whether you need one in your kitchen.

If you’ve been on the Internet recently, you know that the future of stoves is electric. But the future can’t be that rickety, coiled electric stove you had in your first rental apartment, right?

Enter: induction stoves. While these cooktops were first introduced in the early 1970s, induction stoves have just recently started to gain traction because of their energy efficiency, built-in safety features, speedy heating, and more.

How Do Induction Stoves Work?

If you’ve owned either a gas or coil range, you’re probably used to understanding how your stove operates just by taking a quick glance at the cooktop. However, because most of an induction stove’s hardware is located beneath a glass surface, they require a bit of explanation.

Induction stoves heat cookware through electrical induction, while gas and electric stoves rely on thermal conduction. In simple terms, thermal conduction is the transfer of heat from one surface to another through direct contact—i.e. the burner gets hot and heats your pan.

Electrical induction uses a magnetic field to send alternating electric currents from the stove to your pot or pan. Because the heat bypasses the burner and is transferred directly to your cookware, it heats quickly and less energy is wasted.

Induction vs. Gas Stoves

Induction stoves are different from gas stoves because, as mentioned above, they transfer heat differently. The burners on a gas stove create a flame when gas meets air, and cook food through thermal conduction. They’re more common than induction and some home cooks swear they’re the key to great food, but the heat may be difficult to control and recent studies show that they may cause indoor air pollution over time.

While “thermal conduction” sounds like a technical term, it’s actually something that you do multiple times per day. Activities that you probably don’t give much thought to, such as getting into a hot shower, making a cup of tea, or ironing your clothes are all examples of thermal conductivity, as heat is spread through direct contact.

Because induction stoves don’t heat through thermal conduction, there’s no flame or hot burners. This results in a stove with incomparable heat control.

Induction vs. Electric Stoves

Technically, induction stoves are electric in that they’re plugged into an outlet. However, since they work so differently from the typical electric stove, they’re placed in their own category.

The typical electric stovetops found in many rental units either feature coiled rings that get red hot or hidden heating mechanisms locked below a ceramic surface. Just like a gas stove, heat is then transferred to your cookware through thermal conductivity.

Both types of electric stovetops are known for their slow and uneven heating, which can cause hot and cold spots, no matter how high-quality your cookware is. The heat response on electric stoves can also vary, which inevitably leads to longer cooking times and more frustration.

What Is Induction Cooking?

As you can’t see an outside heat source heating up your pan, it can be tricky to understand how induction cooking works.

To put it simply, induction stoves have a copper coil under the surface that creates an electric current when compatible cookware is placed on top. Certain metals create a magnetic current that produces heat where the pan touches the stovetop. Thus, when the stovetop is turned on, a pan will heat almost instantly and the stovetop won’t be hot to the touch.

What Cookware Is Induction Compatible?

Because induction cooking works by creating a magnetic field that heats the pan, not all cookware can be used on an induction stove. This is because some metals, such as copper and aluminum, are nonferrous and won’t create the magnetic field that induction cooking requires.

One method to determine if your cookware is induction compatible is to examine either the packaging or the bottom of the pan you already own for an “induction compatible” symbol, which looks like a coil of wire with 4 loops. However, you can also see if a magnet will either stick to or be repelled by the bottom—if it interacts with the cookware at all, it’s induction compatible.

All Carbon Steel, Stainless Steel, and Cast Iron (enameled or otherwise) pieces should be induction compatible. Aluminum and Copper Cookware are not. Non Stick Cookware may or may not be induction compatible depending on the construction material beneath the non stick coating.

What Are the Benefits of Induction Stoves?

Induction stoves offer several advantages over gas and electric ranges, ranging from (long-term) savings to personal health.

Energy Efficient

Because induction stoves use electrical induction to quickly heat only where a pan touches the stovetop, very little energy is wasted. This means that induction stoves are more energy efficient than the typical gas or electric range, which saves you money on your utility bill and lowers your carbon footprint.

Better for Indoor Air Quality

Recent studies monitoring indoor air pollution have concluded that induction stoves produce less nitrogen dioxide than gas ranges, meaning they’re much better for your body over a long period of time. A study conducted over a 10-month monitoring period found that apartments that switched to induction from gas stoves saw a 35% reduction in indoor nitrogen dioxide emissions.

Built-in Safety Features

Parents of small children know that the combination of a hot stove and small fingers is a constant source of anxiety. But because induction stoves heat food through a magnetic field rather than traditional thermal conduction via contact with a heat source, induction stovetops never actually get hot. In simpler terms: there’s no risk of burning.
