A good resource to learn is any high school physics textbooks, where you will learn why this shit does not and cannot work.

Most textbooks won't explain magnetism to begin with. I'm certain that overunity devices are possible, just not like this.
It will at least introduce magnets, and maybe thermodynamics.

No reason to be certain about the possibility of something like this, which we aren't even close to having.
Do these textbooks still claim gravity is caused by mass attracting mass, or warping space-time gibberish? Pseudo-physics is hardly a good source of anything.
