Even if everyone had equal prep time, I still give it to batman.
Batman and Ironman are both brilliant individuals, where Ironman is a brilliant scientist and engineer, Batman is a brilliant stratigist.
I imagine Ironman (with prep time) would construct armor that would be able to withstand Magneto's onslaught, But Batman would still be one step ahead of him.
Magneto's shields were explained back in 1992 during a one shot. It said that it identifies the polarity of an object and generates an equal polarity that repels the object. If it's neutral, it removes an electron from the object to give it a positive charge (similar to how static cling works) then generates a positive charge that repels the object. Remember, Magnetism works on everything, not just metals. That's how static cling works.

Yeah and so is an Asgardian god with a magic hammer.
Face it. Magneto wins. Iron Man can live to fight another day.
Hehe ok ok... I'm a bit surclass here, then go for Magneto but I will always think IM can do it. Damn IM his a freaking destruction machine, a incredible sharp mind and one of the best marvel hero, I put him at the lvl of Hulk or Thor at the difference he is not using the same way to win.
P.S.
We can't polarize energy like light or laser. They don't have atom so don't have electron than can't be affect by magnetism, light are just a wave.
a laser is a form of energy Magneto can manipulate, and light is too.
Magneto's powers are sufficients to kill Batman with ease and at the same time defeat IM.He can manipulate gravity on a decent level, and use that power to block IM and stop him from flying, then hold him down and proceed into destroying the armor piece by piece.
