Wouldn't it be more efficient to use that energy to destroy Mars and build start building a Dyson swarm from the debris?
Let's do a quick estimate. Destroying a Mars-like planet requires expending the equivalent of its gravitational self-energy, ~GM^2/R, which is about 10^32J (which we could easily obtain from a comet 10 kn in radius... consisting of antimatter!) For comparison, the Earth's magnetic field has about 10^26J of energy, a million times less. I leave it to you to draw the conclusions.
