HAhaha, Bad hair day?

Seriously, if the Earth can be utilized as a magnetic force then there is no gravitational pull if working with the opposite magnetic element.
SUCH AS: Putting two polarized magnets together (repelling each other) and injecting a two pronged circuit completed with coiled copper wires attached, this video shows it as free energy, for charging the phone.

QUESTION: why does each wire need to be coiled?
Do the coils act like an intensified distance, accelerating the magnetic waves into energy? Is that why it works?

Cool!

I think I need to try this experiment at home. Sounds like a fun homeschool project. Let's prove free energy right!
