Induction and electric cooktops offer power, precision, and performance when delivering fast cooktop heat and superb heat control. Knowing the difference between the two can help you make a better decision for your kitchen. One of the simplest ways to tell them apart is by checking if a magnet sticks to the cooktop—if it does, it's induction. You can also turn the cooktop on and observe if the surface heats up; if it does, it's electric.

Induction cooktops use electromagnetic radiation to heat compatible pots and pans
The electromagnetic field generated by an induction cooktop is what causes the cookware to heat up and your food to cook. This field is created by an alternating current of electricity passing through a coil under the cooktop's surface. The cookware must be magnetic and made with a ferrous material to interact with the electromagnetic field. Stainless steel, cast iron, and enameled cast iron cookware are all compatible with induction cooktops. If your cookware is not magnetic, it will not work on an induction cooktop, and you'll need to invest in new pots and pans or an induction converter disc.
There are several ways to determine whether you have an induction or electric cooktop. One way is to place a magnet on the cooktop's surface; if it sticks, it's an induction cooktop. Another way is to observe whether the cooktop's surface heats up when turned on; if it does, it's an electric cooktop. Electric cooktops have metal coils underneath a glass or ceramic surface that conducts an electrical current to radiate heat. The coil becomes hot and glows due to electrical resistance, transferring heat through the glass or ceramic surface to the cookware. This means that any type of cookware can be used on an electric cooktop, whereas induction cooktops require magnetic cookware.
Induction cooktops offer several advantages over electric cooktops. They heat up and cool down much faster, making them the fastest way to cook. They are also easier to clean since the surface usually stays cool, resulting in less burnt-on food. However, induction cooktops may be more expensive and require compatible cookware or an induction converter disc. On the other hand, electric cooktops are more common, affordable, and widely available. They offer centralized heat, and their slower heating and cooling rates may be preferable in certain situations.

Electric cooktops heat the surface, which then transfers heat to the pan
Electric cooktops, also known as radiant cooktops, heat the surface, which then transfers heat to the pan. They are different from induction cooktops, which use electromagnetic fields to generate heat directly in the cookware. Induction cooktops have a cooler cooking surface than conventional stovetops, as the cooking surface itself is not heated.
Electric cooktops have metal coils underneath a glass or ceramic surface that conduct an electrical current to radiate heat. The coil becomes hot and starts to glow due to electrical resistance. It then transfers heat through the glass using infrared energy. This means that the burner holding the pot or pan is what gets hot, and the food is cooked by the transfer of heat between the cooktop and the pot.
Because the surface of an electric cooktop is what heats up, spills are more likely to get stuck or burnt on. This makes cleaning an electric cooktop more challenging than an induction cooktop, as the surface of an induction cooktop usually stays cool, resulting in less burnt-on food.
Electric cooktops are also slower to heat up and cool down than induction cooktops. This might not be a significant factor for some people, but it is something to keep in mind, especially if there are children or pets in the household.
To determine whether a cooktop is electric or induction, one can observe whether the surface heats up when turned on. If it does, it is an electric cooktop. Additionally, a magnet will stick to an induction cooktop but not an electric one, as induction-compatible cookware must be magnetic.

Induction cooktops only heat the cookware, so they cool down faster
Induction cooktops utilise electromagnetic fields to generate heat directly in the cookware, while electric cooktops rely on an electrical current that heats a metal coil under the glass or ceramic surface, which then transfers heat to the cookware. This distinction is key to understanding why induction cooktops cool down faster.
Induction cooktops only heat the cookware and not the surrounding air or cooktop surface. This is because induction cooktops use electromagnetic radiation, with an alternating current of electricity flowing through a ring to the cookware, which then begins to heat up. As a result, there is no residual heat with an induction cooktop. On the other hand, electric cooktops have residual heat, which is why they are often equipped with indicator lights to warn users that the surface is still hot.
The absence of residual heat in induction cooktops means that when the power is turned off, the cooktop cools down much faster than an electric cooktop. This is an important safety feature, especially for households with children or pets. The faster cooling rate of induction cooktops also means less energy is wasted, as the cooktop does not remain hot for an extended period after cooking.
In addition to safety and energy efficiency, the faster cooling rate of induction cooktops can also be advantageous in certain cooking scenarios. For example, when preparing dishes that require quick temperature adjustments, an induction cooktop's ability to cool down faster allows for more precise temperature control. This can be particularly useful for techniques such as melting chocolate or making candy, where precise temperature control is crucial for achieving the desired results.
It is worth noting that while induction cooktops cool down faster, they also tend to heat up faster than electric cooktops. This is due to the direct transfer of heat to the cookware, without the need to heat the cooktop surface or surrounding air. As a result, cooking with an induction cooktop can be more energy-efficient and time-saving, especially when preparing meals that require rapid boiling or quick temperature changes.

Electric cooktops are slower to heat up and cool down
Electric cooktops have slower rates of heating up and cooling down compared to induction cooktops. This is because induction cooktops only heat the cookware, whereas electric cooktops heat up the surface of the cooktop, which then transfers heat to the cookware. This means that induction cooktops are more responsive and can achieve the desired temperature more quickly.
There are a few ways to determine whether a cooktop is electric or induction. One way is to place a magnet on the cooktop; if it sticks, it is an induction cooktop. Another way is to observe whether the cooktop heats up when turned on; if it does not, it is likely an induction cooktop, as these only heat up when a compatible pot or pan is placed on them. A third way is to place a small amount of water or food on the cooktop and turn it on; if the water boils or the food begins to cook, it is an electric cooktop.
The slower heating and cooling times of electric cooktops can be a disadvantage, especially when compared to the faster heating and cooling of induction or gas cooktops. However, electric cooktops have the advantage of being more affordable and easier to install, and they can also provide a steadier heat output with less temperature fluctuation. Additionally, any type of cookware can be used on an electric cooktop, whereas induction cooktops require magnetic cookware.
The slower cool-down period of electric cooktops can be a safety concern, especially for those with children or pets. It is important to allow electric cooktops to cool down completely before touching them or placing them in storage. It is also important to use common sense and not touch the cooktop with your hands to test if it is on, as this can be dangerous.
