What is Induction Heating?

Induction heating involves using an alternating electromagnetic field to heat metallic objects by inducing electrical currents within them. Here’s how it typically works:

1. Induction Coil: A coil generates a magnetic field when an electric current passes through it.
2. Electromagnetic Induction: When a conductive material (like a metal workpiece) is placed within this magnetic field, it experiences induced currents.
3. Heat Generation: The resistance of the material generates heat, quickly achieving the desired temperature.

This process is highly efficient and can be precisely controlled, making it a valuable technique in electronics manufacturing.
