I thought that it is a very simple scheme.
And explanations may be needed only when you make it start working.
The device is dangerous (the same as tesla coil).
I am not responsible for any damage that may happen.
By the way 2N3055 has Col-Emitt= 70V
So you should plug 7-12 V. But not more.
In this cause you can't get hight power and long spark
but cool electricity and magnetic field only
