Induction Cooktop: How It Works & How to Choose the Right One

October, 10 2026


How Does an Induction Cooktop Work?

Unlike a gas stove, an induction cooktop does not produce a flame. Instead, it uses a copper coil located beneath the glass cooking surface.

When the cooktop is switched on, electricity passes through the coil and creates a rapidly changing magnetic field. When compatible magnetic cookware is placed on the surface, this magnetic field generates electrical currents inside the cookware. The resistance of the cookware converts these currents into heat, which cooks the food.

  1. Compatible Cookware

Before buying, check whether your existing pots and pans are induction compatible. If they are not, you may need to purchase suitable cookware separately.
