How does induction heating work

Many people may be curious about the work of induction heaters, let me unravel the mystery of induction heaters for you:

induction heater

1.The shell material is plastic and fiberglass (This material can resist high temperature).

2.The interior is mainly composed of four parts: circuit board, transformer, heat sink, and high-speed cooling fan.

3.The working principle of an electromagnetic induction heater is based on Faraday’s law of electromagnetic induction. When a conductive object (such as metal) is placed in a changing magnetic field, an electric current, known as an eddy current, is induced within the object. This eddy current generates heat as it flows through the conductive object, thereby heating the object. This is the basic working principle of an electromagnetic induction heater.In practical applications, an electromagnetic induction heater typically uses a high-frequency alternating current (AC) source to generate the changing magnetic field. This high-frequency AC source is connected to a coil, and when the current passes through the coil, it creates a strong magnetic field around the coil. When we place a conductive object (like metal) in this magnetic field, eddy currents are induced within the metal, causing it to heat up.The advantage of this method of heating is that it can heat objects very quickly, and the depth of heating can be controlled by adjusting the frequency of the AC source.
