How Induction Cooktops Work

Induction Cooktops Work

Over the last few years, induction cooktops are slowly becoming more popular than before. That’s because of induction cooktops are quite useful when compared to other forms of cooking. But do you understand what an induction cooktop is? Or better yet, do you even know how it works? Thankfully, this article is in your best interest.

With that in mind, we are going to discuss all the relevant information that you will need to know before buying the best induction cooktop in the market. That includes how it works and so much more. So, let’s get started, shall we?


What is induction?

Induction, also known as electromagnetic induction, is the production of electric current using an electrical conductor. More importantly, the electric current typically results from the changes in the magnetic field. I know that’s a lot to digest but bear with me. I’ll simplify the concept as much as possible.

Electricity and magnetism are two different things, but they arguably have the same origin. They both originate from an underlying phenomenon known as electromagnetism. What’s more, the changes in the magnetic field lead to the generation of electric current that is harnessed into the electrical conductor. Similarly, any changes in the electric field will lead to a magnetic field. Keep that in mind for you to fully understand how an induction cooktop works.

What is an induction cooktop?

Basically, an induction cooktop looks similar to a ceramic cooktop. However, the induction cooktop has different zones where you can place the pots or pans of various sizes. In addition to that, the induction cooktop also features a sturdy and heat-resistant glass type ceramic plate. That’s where the user places the pan or pots when cooking.

Just below the plate, there’s a layer that consists of an electromagnetic coil. The coil is made of metal, and it’s controlled electronically. In fact, this is the main component that’s responsible for the heating process in the induction cooktop. Now that you are up to speed, let’s take a more in-depth look at how induction cooktops work.

How do induction cooktops work?

How the induction cooktops work is relatively easy to understand. The magnetic field that’s produced by the coil also penetrates the metal of the pan as well. The changes in the magnetic field will cause an electric current that will flow through the material of the pot too. The current that will be induced on the surface of the pan is known as the eddy current. This type of current is a bit different when compared to the current flowing in the electric wires.

Actually, the eddy currents move in loops, and they typically occur around metallic fields that have been formed due to changes in the nearby magnetic field. The eddy current will travel all through the structure of the pan while dissipating energy that’s typically in the form of heat. The heat will then increase the pan’s temperature hence cooking the food content. Heat moves through convection and conduction.


When you switch on the pan and place your hand on top of it, you won’t feel any heat. It sounds weird considering the experiences you’ve had with other cooking appliances, right? Well, here’s the science behind it; for the temperature to rise on the induction cooktop, it will need a suitable pan that can induce a current hence leading to dissipation of heat. But before you try this experiment, you need to pay attention to the warning below.

Warning: As much as placing your hand on top of the cooktop will not necessarily heat up, the surface might be hot. What do I mean? There’s a slight chance that there was a pan that was previously on the cooktop just a few minutes ago. So, it’s best to make sure that the cooktop is not hot before you try to put your hand on top of it. Other than that, this device is quite safe to use around the kitchen. However, it’s not the best fit when you are dealing with kids.

Benefits of using an induction cooktops

There’s a reason why the induction cooktop is quite popular. That’s because these devices will improve your efficiency in the kitchen. That’s not all!

  • It’s very energy efficient: I know this might sound contradictory since the induction cooktop uses electricity, but it’s true. In that, the induction cooktop transfers all the energy to the cooking pan while at the same time minimizing energy loss in the process. Meaning, it’s pretty useful in conserving energy use, especially when compared to other electric devices.
  • The device is quick: The fact that all the energy is able to transfer energy directly to the cooking pan, also means that the pan will heat up faster. Therefore, you can finish up your favorite dish in a matter of minutes.
  • Easy to clean and maintain: we all know how messy your kitchen can get all thanks to your cooking device. However, it’s all about to change when you decide to use this device. The induction cooktop is quite easy to clean and maintain.

The drawback of using the induction cooktops

There’s one major disadvantage that you will have to face when using these induction cooktops. That is:

  • Only use compatible devices: when it comes to cooking with the induction cooktop, you can only use pans and pots that are compatible. The kitchen appliance should contain iron, for instance, stainless steel. That’s because iron is the only metal that can effectively conduct eddy currents and also generate a magnetic field in the process.

To wrap it all up

In a nutshell, purchasing an induction cooktop is one of the smartest things you will do this year. Not only will it speed up your cooking process, but it will also take care of your electric bill. What’s more, you don’t have to worry about the cleanup process after you’ve prepared your favorite dish. But don’t just take my word for it! Check out the best induction cooktops in the market today to get one for yourself.
