How to build an induction heater and how does it work?

induction heaterAn Induction heater is a tool that uses heat to harden, soften or bond metals and similar conductive materials. The induction heater is a peculiar device that allows rapid heating, which makes the job easier, productive and more efficient.

Moreover, this particular induction heater doesn’t need fossil fuels and can heat objects of various shape, so it’s pretty flexible and useful.

But, how does this tool operate? Quite simple. It surrounds the object that needs heating with a coil carrying, high-frequency AC current. ThisĀ entire setup is like an enormous transformer with a shorted secondary.
Additionally, it’s not complicated to build one. The heater uses a few common components and demonstrates the high-frequency magnetic induction quite successfully. Check it out!
