Induction cooktops require cookware that has a magnetic base to work effectively. Stainless steel alone is not inherently magnetic and will not work on an induction cooktop unless it contains magnetic materials.
If you want to use an existing pot on an induction burner, you can check if it is already labeled as "induction-compatible" or "induction-ready." Many modern stainless steel pots and pans are designed to work on induction cooktops and will have a magnetic base.
If your existing stainless steel pot is not labeled as induction-compatible, you can use a magnet to check if it contains magnetic materials. Place a magnet against the bottom of the pot; if it sticks firmly, it likely contains enough magnetic material to work on an induction cooktop. If it doesn't stick, it is not suitable for induction cooking.
If your pot is not induction-compatible and you still wish to use it on an induction cooktop, there are induction interface discs available in the market. These discs are made of magnetic material and can be placed between the cooktop and your non-magnetic pot to make it compatible with induction heating. However, using an interface disc may not be as efficient as using cookware designed specifically for induction cooking, as there may be some heat loss during the transfer.
To ensure the best performance and safety, it is recommended to use cookware that is specifically designed for use on induction cooktops. Many stainless steel pots and pans are induction-compatible, and you can find a wide variety of options available in the market.
