What is an induction cooktop vs electric cooktop?

Unlike standard electric cooktops (or gas), induction cookers heat the cooking pans only.

The benefits of induction cooking include efficient heating (saving energy costs) and a surrounding surface that remains cool (safety).

The main reason for such advantages in cooking is that induction cookers use an electromagnetic field to generate heat vs electric cooktops, which rely on radiant heat.

I wrote about choosing a portable induction cooktop where you’ll find examples of this type of cooking system and how it differs from electric cooktops and other traditional cooking systems.

How to use an induction cooker

1. Use induction suitable cookware

First, you will need induction-ready cookware. If you aren’t sure whether your existing pans are induction-ready, use this trick…get a magnet and see if it sticks to the base of the pan. If it does, you have a compatible pan. If not, you need to get yourself a new pan to use with this type of cooktop.

The thing is to use a pan size that matches the coil. When centered the pan should completely cover the coil.

Ensure the pans sit well and don’t wobble when in contact with the cooktop. This means you need flat-bottomed pans, as these will sit level.

2. Ensure you use non-metal utensils with your cookware

To avoid any current flowing through your body, use only nonmetal spoons or utensils, e.g. made from bamboo or silicone.

3. Operate controls to select cooking zone and heat settings

The cooker will have an ‘on’ switch to turn it on (depending on the model). If you aren’t sure check the instructions that came with the appliance.

Place the pot or pan on the induction cooktop, select the relevant cooking zone and then choose the temperature setting. The cooktop will detect the ferromagnetic base and start to heat immediately.

Rather than knobs, modern cooktops have controls sensitive to touch, like this one in the video. Although cooktops will slightly differ, you might find the following helpful…

How does induction cooking work?

Induction uses magnetism to generate currents and this creates heat. 1

What makes induction heating different from all the others used for cooking? The heat is generated inside the object — in this case, your cooking pan – rather than from an external burner.

Heating your cookware in this way requires a high rate of vibration for enough energy to cook food.

To achieve this, induction cooktops have a series of electronic devices to increase the current and frequency so that a high-frequency AC passes through the induction coil to produce a rapidly alternating magnetic field. (The devices and wiring are designed to ensure home and appliance safety).

For this type of heating, cookware containing iron will produce heat.1 Iron conducts electricity but does so relatively poorly. In other words, it has enough resistance that the current converts to heat.

Most of the heat used to cook food on an induction cooktop comes from this electrical resistance, and the rest comes from heat generated by changes in the magnetic structure of the cookware

For this reason, induction cooktops require ‘induction-ready’ cookware — a type with a special base in the pan to function properly.

How do I keep scratches off my induction cooktop?

If you’ve noticed scratches forming on your induction cooktop, try cleaning it with a damp microfiber cloth and then working in a smidgen of induction-specific cooktop conditioning cream. You can then polish it with a dry cloth. This conditioning will not only improve the look but also help avoid further marking.

Scratches affect the look of an induction cooktop more than anything else.

There are certain steps that you can take to prevent scratches from appearing.

  • Make sure that you only use liquid-based cleaners for your stovetop. Powdered cleaners typically come with a number of harder particles that could damage the glass surface as you rub the cleaner around.
  • Check the bottoms of your pans to make sure they are smooth, as any rough, sharp edges could damage the area in contact with the cooktop.

Where your pans have less than smooth bases, you can try placing a piece of parchment paper designed for baking between your pans and your stovetop. This will give you an added layer of protection without affecting the heat transfer.

Using cast iron on induction stoves

Does cast-iron cookware work on induction stovetops? Cast iron is certainly a cookware type you can use on induction cooktops. The problem people find is that the base of cast-iron cookware, in contact with the cooktop, is rough and can leave marks on the glass cook-top.

Using a non-stick pan on an induction stove

Can we use a non-stick pan on an induction stove? Yes, but not all nonstick cookware can be used on an induction cooktop. You need the type with a magnetic type of metal in the base. Look for cookware labeled ‘induction ready’, ‘induction compatible’, or ‘suitable for induction cooktops’.

Induction ready sets are included in my buyer’s guide to ceramic nonstick cookware and I also look specifically at ceramic nonstick types.

Manufacturers design these for induction cooktops and so the bases should not mark the glass cooktop.

Other induction ready cookware to use

Due to the rise in the popularity of induction cookers, many popular brands now make pans suited for cooking on induction systems.

GreenPan is one of many brands with induction-ready cookware. It is a trusted name in the home cooking world and so is one worth considering if you want a product that will work on all types of cooktops. See my reviews of GreenPan’s latest designs that include induction compatible cookware.

Can you burn yourself on an induction cooktop?

Not only is the induction cooking system more efficient than traditional cooktops but families feel safe with the cooktop.

Dangerous situation in the kitchen. Child playing with a stovetop.

This is because the surroundings remain cool to touch while the cooking is in progress. Only the pans are heated. The thing to note is that the contact area of a pot on an induction cooktop will be hot to touch during and directly after use. This is because some of the heat from the pot will be transferred to the cooking surface (see my article on when induction cooktops get hot).

So, in answer to the question: Can you burn yourself on an induction cooktop? Yes, you may burn yourself on an induction cooktop, but only if you touch the spot where the pot contacts the cooktop while (or a short time immediately) after in operation. Outside this, the induction cooktop surface will remain cool to touch unlike a gas or electric range (radiant heat) that will be hot to touch and cause burns for a considerable time after you’ve turned it off.

How to clean an induction cooker

Because the stovetop stays cool, splatters of sauce and the like won’t burn into or crust onto the cooking surface, making cleanup so much easier than with most traditional types.

While induction stoves are simple to clean, what you do need to avoid when cleaning are surface scratches and scrapes.

Cleaning An Induction Cooktop – Step-By-Step

  • First – Wipe with damp sponge. Remove surface cooking residue from the cooktop (make sure it’s not in operation and the area in contact with the cookware has cooled).
  • Second – Apply a smidgen of induction-safe stovetop cleaner, such as Cerama Bryte (you can get this at Amazon – see here), and rub until the remaining residue and marks are removed. Use a damp paper towel or cloth to remove excess.
  • Third – Polish with a soft dry cloth. Simply use a paper towel, dry cloth, or kitchen rag to dry and polish the surface.

What will help make this process easier is a quality cleaning product.

Make sure that you avoid products such as chlorine bleach-based cleaners, metal cleaning pads, dishwashing agents, or powdery cleaners that could damage your induction surface.
