How to Make a 12V Pocket Induction Boiler

The induction coil is capable of extremely quickly heating metal objects. If you assemble it according to the proposed scheme, you can get an induction boiler for boiling water in a steel container such as a cup or saucepan. This is quite a working device that can be used in practice.

Materials:
