During the last couple of months I seen some different threats about induction past my way. In none of the post I have seen any warning about the danger of this technology. While working with induction especially the DIY devices, you produce in the worst case a lot of EMF (electromagnetic field) radiation.

This radiation is dangerous to your health if you are too close to the source or carry a pacemaker.

So don’t wonder if grandpa is acting silly next to the forge, or you not able to reproduce yourself any more.

In some countries they have research results that even an induction stove of some brands is not safe any more.

Please consider this risks before you start to re-build some YT example and take some measurement on your existing equipment.

Have a nice and safe day. Cheers, Hans

It is also not safe to use induction heaters if you have any metal bits in you like plates, screws, metallic replacement parts... Or so it has said on a couple induction machines I have used. 

Good point to bring up Hans.
