How to make an induction heater! Do you know?

Using the principle of induction heating, you can burn iron rods in 3 seconds! How to make an induction heater? 

Let me first share a wonderful experiment, please see the picture below:

Now, do you understand the principle? There are no friends who want to make it? Because you may not be familiar with it, you can not complete it. If you want to refer to the completed induction heater production, please click induction heater.
