Can my son's plan to terraform Mars work?

My son presented this plan to me and I'm not clever enough to refute it. Smart people of Reddit to the rescue!

The plan:
1. Build Tesla coils on a grid to ozonate the oxygen in the CO2.
2. This helps provide protection from the sun's radiation and would in turn break apart into oxygen (like on Earth)
3. The Tesla coils could also be used for their original purpose of wireless transmission. 
4. Put electro magnets in orbit of the planet to form a magnetosphere of sorts to protect against solar flares, solar winds, and meteors.

Turning a thin atmosphere of CO2 into a similarly-thin atmosphere of O2 accomplishes little.  You would need to liberate O2 from somewhere else to provide a thick enough atmosphere for humans.  You would likely have to process millions of tons of Martian soil to liberate O2.  This would take many decades and the energy cost would require hundreds, perhaps thousands, of gigawatt fission or fusion reactors to power it.

This is all incredibly unfeasible at our present level of technology.  A century or two from now...who knows?
