Understanding Induction Heating Systems
How Induction Heating Works
Induction heating systems heat metals fast and well. They make a magnetic field that changes. When you put metal in this field, eddy currents flow inside it. The metal gets hot because it resists these currents. You can control the heat very accurately.
Induction heating uses Faraday’s law. This law says a changing magnetic field makes a force in a loop. The coil’s current creates a magnetic field that goes into the metal. This field makes eddy currents, which heat the metal.
The skin effect is important too. It makes most heat stay near the metal’s surface. This helps you heat only the part you need. It saves energy and keeps things safer.
- Induction heating uses electromagnetic induction to heat metals.
- It makes eddy currents in the metal, which heat it up.
- This method lets you heat one spot and control the heat easily.
