How Do Induction Cooktops Work: A Practical Application of Electromagnetic Induction?

Induction cooktops are neat kitchen gadgets that cook food in a unique way. They use something called electromagnetic induction. This might sound complicated, but here’s how it works:

When you turn on an induction cooktop, it creates an electric current in a copper coil. This current makes a changing magnetic field around it.

This changing magnetic field then produces an electric current in your metal cookware, like pots and pans. The cookware heats up because it resists this electric current.

Key Ideas:

  • Faraday's Law: If a magnetic field changes, it can create an electric force.

  • Lenz's Law: The electric current that gets made pushes back against the original change.

Example:

A cast iron pan is great for induction cooking. It’s magnetic, which means it can easily use the heat that’s made!
