How to Choose Induction Cookware: Check with a Magnet!

Can You Use Just Any Pot on an Induction Cooktop?

Induction cooktops heat cookware directly through electromagnetic induction, which means not all pots are compatible. Only pots that respond to magnetic fields will work. Luckily, there’s a simple trick anyone can do: the magnet test.

1. Why Does Cookware Material Matter?

Induction cooktops use the principle of electromagnetic induction. A coil underneath the surface generates a magnetic field that creates eddy currents in the cookware, which are then converted to heat through resistance. This means the cookware must be made of magnetic material to generate heat.

2. The Magnet Test: Easiest Way to Check Compatibility

Place a magnet on the bottom of the pot. - If it sticks firmly → Compatible with induction - If it doesn’t stick → Not compatible

Even stainless steel may not work depending on the type. Aluminum, copper, glass, and ceramic cookware are generally not compatible unless they have a special induction-ready base.

3. Look for the Induction Symbol

Many pots will have markings such as “IH,” “Induction,” or a coil symbol on the bottom. This indicates manufacturer-certified compatibility with induction cooktops and is even more reliable than the magnet test.

4. A Flat Bottom Is Just as Important!

The closer the pot bottom sits to the induction surface, the more efficient and quieter the heating. Warped or uneven bases can lead to poor heat transfer, noise, and energy waste.

5. Recommended Materials & Features

  • Magnetic stainless steel (18-0): Common and sleek
  • Enamel-coated cast iron: Great heat retention with stylish designs
  • Multi-layer base: Often combines aluminum for conductivity with a magnetic layer for induction compatibility

Conclusion: One Magnet is All You Need!

Choosing cookware for induction doesn’t have to be complicated. A simple magnet test instantly confirms compatibility, and checking the back for an induction mark gives you extra assurance. Using the right cookware ensures optimal performance, safety, and efficiency with your induction cooktop.
