What is Induction Cooking?

Induction cooking has existed for decades, but only recently has improved demand driven prices down and merchandise selection up. But is still remains a puzzle to a lot of cooks, particularly in the United States.

Cooking typically includes the use of heat to food. But unlike conventional cooking technology, such as gas and electric stoves, that involve generating substantial heat that's then transferred to the cooking container, induction cooking uses the cooking vessel since the original generator of the cooking heat. 

To comprehend how it does so, it is vital that you understand electromagnetic induction -- the science behind this cooking method.

Electromagnetic Induction

This is when a shifting external magnetic field induces a current in a conductor. It occurs as a result of the magnetic pressure located on the free electrons in the electrical conductor materials. The changing magnetic field could be a moving magnet or an electromagnet.

The strength of the magnetic field depends on the total amount of current. The opposite of this can be electromagnetic induction, where an electric current is induced in a wire or other conducting object by a shifting magnetic field; and among the practical applications of the happening is induction cooking.

How does Induction Cooking Work?

Induction cooking uses induction cookware, including pots pans, which can be especially made to be used on electromagnetic induction range tops. The induction array tops include a highly effective element composed of a high-frequency electromagnet.

Once an induction cooktop is connected to the mains power and switched , an alternating current is passed through this electromagnet, causing a magnetic routine -- which generates eddy currents (a loop flow or flow of power) within the ferrous substance of which induction cookware is normally made.

The main distinction is that here, the cooking heat is created directly in the cookware itself, not in any part of the induction cooker.

A higher frequency of AC flowing via the induction coil is expected in order to make a rather high speed of change in the magnetic field necessary for generation of helpful cooking heat.

To achieve this, induction cooktops come with a series of electronics, such as a transformer, a rectifier and inverter, which tremendously increase the AC in the mains electricity supply and its own frequency whilst protecting the appliance wiring and your property.

Induction Cooking Units

Induction cooking components are sometimes a built-in surface in the kitchen, either part of a stove, or a standalone surface component. Constructed and range cooktop units usually come with multiple elements, just like the separate burners on gas ranges.

The standalone components are generally single-element, but in addition, there are a few that feature dual components. Each of the components have the exact same basic design: electromagnet fitted under a smooth, heat-resistant glass-ceramic sheet -- which makes it effortless to wash.

The cookware (pan or pot), together with its material, is put on the ceramic glass surface to heat up. If purchasing an induction monitoring unit, you need to consider the size of this device, the area available in your kitchen, and also quantity of cooking elements, as well as safety and features like touch controllers, automated pan size recognition, timer, child lock, boost function and automatic security shut-off.

Iron does a fantastic job of converting induced current (eddy current) to heat. This is the reason induction cookware is made from iron-containing substance -- stainless steel or iron. Iron is not a very good conductor of heat as it has a higher resistance.

But this is a benefit in regards to induction heating system. When a current is passed through a material with a high resistance like iron, much of it is converted into heat. The enhanced magnetic permeability of iron decreases skin thickness, thus focusing the induced current near the surface of the metal.

This further increases the electric resistance, boosting heat manufacturing capability. The high resistance of ferrous cookware material is actually responsible for most of the heat used to cook foods in induction cooking, however some heat can also be produced by magnetic hysteresis or changes in the magnetic structure of this material.

Induction Cookware

Generally, induction cookware may be used in different stoves. Some packaging or brands have symbols to indicate compatibility with gasoline or electric heat. However, any cookware with a high-ferrous metal material at the bottom may be utilized on an induction cooktop.

However, not all of stainless steel cookware can work on an induction cooking surface. Just these stainless steel pots and pans using a magnetic-grade base will work in an induction cooktop.

Pros and Cons of Induction Cooking


  • Induction cooking is extremely fast. Because the pan or pot is the beginning point of this heat, it requires much less time to allow the heat to reach to the food. In fact, it takes 25-50 less time to heat water and cook various dishes. This makes it a more cost effective and time efficient option.
  • Induction cooking is also quite precise. Its ability to allow precise control of heat is probably the most crucial quality of this cooking technologies. Induction cooktops are incredibly responsive, allowing accurate control of temperature increments while also providing better performance at low heat settings. This makes it an excellent solution for those sensitive dishes that require consistent heating.
  • Less wasted heat. Induction cookers utilize 85 percent of electricity to warm food, whereas gas cookers use 45% (less than halfan hour of gas to cook, together with the remainder being waste heat which warms up the kitchen. Having an induction stove, you may enjoy a lot cooler kitchen that isn't only healthful but also environmentally friendly.
  • Safer. Since there's no waste heat, fumes or open flames, induction cooking is extremely secure and you don't need to worry about burnt fingers or danger with kids around. Preventing the induction cooktop switched on after you have removed the pot poses no threat whatsoever.
  • Simpler to wash. An induction cooktop is not only attractive, less inefficient and safer, but its sleek glass ceramic surface allows for easy clean-up. You won't need to manage obnoxious gas boilers.
  • Ease of setup. Induction cooktops are typically thin, making the installation easy and convenient.

Cons :

  • Only cookware that's compatible with induction heating can be used.
  • The cookware need to have a level base since the cooktops are flat, and this can be restricting.
  • Induction cooktops are typically more costly than gas or electric ranges. But investing in induction cooking components and cookware is still well worth it given its own energy savings and other advantages.
