Dark Elf is going to have a shocker coming for him, is all I've got to say.
The MunchKING is Back! And he is AWSOME!
I would use my powers to drive around in a custom car that I control just through my magnetism. Then I would stop at gas stations just to brag to the attendants that my car doesn't need gas. And if they contradict me, things will happen!
Agressively discourage terrorism, protect people, Make money. Garner power and influence
Besides the mental shenanigans mentioned earlier, he's also bent light around himself and become invisible.
Personally, I'd do the celebrity thing, get rich, then hire the best lawyers in the country to negotiate a contract with the government that licences me to act as an agent of the military but at the same time gives me the right to refuse an order I think is unacceptable. I want to help but I don't want to be a puppet of whomever happens to be in office at the time.
It's actually in the military code that you HAVE to refuse Illegal orders. Unethical is more of a grey area if it isn't actually illegal.

If we are taking Magneto's powers at face value along with their ridiculousness then you are essentially a god. You don't need to work for the government, you can pretty much be the government and no one would be able to stop you. Comics Magneto can make air pockets in space, so it's not like he'd get hit with nuclear radiation if someone nuked the country to get rid of you.
You'd just become a benevolent global dictator.
Don't forget drop a football stadium on the white house if Trump gets elected.
I don't think that's fair, people would stop sending tanks and drones after a Magneto style dictator after they seem him crunch them into a ball with minimal effort then throw it through their parliament/palace. I think once you establish you're in a completely different league then people will give up or fall in line.
I don't personally want to be a dictator, killing people, taking responsibility for the world, etc. Also, I feel I'm neither justified nor equipped to direct the fate of the human race.
Mileage may vary.
Not sure what I would do with Magneto's full powerset other than 'make stupid amounts of money (there are any number of legal ways to do this with Magneto's powerset) and travel the world for the remainder of my life.'

"Why throw punches when you can be making everyone around you sterile mutant corpses?" - Pendaran, regarding Dr. Fate
I might see if I could use the powers for medical treatments. I've always pondered those in the comics who just use their abilities to fight.
A Green Lantern physician for instance could save many. Remember when Clark saved Lois with heat vision (BTW, that was ridiculous). Having watched good people die of things we cannot fix how - I would see if I could treat folks. An Atom could do microsurgeries for instance.
Soranik Natu was a doctor Green Lantern and used her lantern powers for medical purposes as her first act as Green Lantern.
