A question came up between me and a friend, the question revolved around a what if scenerio involving a fight between Iron man and Storm. While pondering it he stated that because iron man's suit is metal that it would make him an obvious conductor for lighting attacks from storm, and that made me  wonder about his forcefield and if it would protect him from such an attack.
 
Now, I remember hearing about Iron Man having an electromagnetic forfield around his suit, and i looked iron man up here on comicvine, and other websites and they all stated that he does have this type of forcefield but none of them elaborated on the extent of his forcefield.
I've seen electromagnetic pulses used to create forcefields before in other mediums, for example in the animated movie Batman Gotham Nights, Lucius Fox give Bruce Wayne an electromagnetic repulser of some sort that is explained to only reflect metal objects coming at him at high speeds i.e. bullets, and in Metal Gear Solid 2 there is a character named Fortune who also has a simular gizmo that creates a electromagnetic field allowing bullets to vier away from her while in battle. Also in the same game while Revolver Ocelot was wearing the device it allowed a shot from a railgun(wich is a gun that shoots some form of electicity from its barrel) to also vier away from him. I know these are not iron mans pulse so they don't have any continuity with iron man.

But my question is what is the extent of iron mans forcefield? Does it only block metal objects thrusted at him at high speeds? or does it also protect him from metal objects used to attack him at slower speeds like knives and swords? Can it also protect from non-metal objects? Can it protect him from different forms of energy blasts? and is it able to block electricity attacks?

Tony Stark is a pretty smart guy, I think he would build the suit insulated against lighting strikes. After all airplanes get struck by lighting everyday and it doesn't effect them. So he probably wouldn't even need the forcefield.

probably, he does fly just as high as planes and even higher at times, so he probably did take all of the obvious precations when building the armor, taking airplanes and maybe even spaceshuttles in account.
 but im still wondering how his forcefield has worked into the comics and what it is able to deflect.

Iron Man's suit is not completely vunerable to lightning, here he is taking direct blows from Thor:





He was damage from the blows, but far from taken out. And that was after several hits from Thor.

Here a wrist mounted Force Field with enough strength to block missles



Contains Electro with his force field





Using "Magnetic Field" to levitate all metal objects






On a side note, he has immunity to Magneto's powers:

thanks for the examples.
what is going on in that last picture? i can't figure out what exactly is happening.
how is he able to become immune to magnetos power?
does it have to do with his magnetic field canceling out magnetos magnetic field? how is that explained to work?

I'm not sure the context of the last scan actually. I just know that Magneto wasn't able to use his powers. I'm not sure if its due to Iron Man's magnetic field or if he uses some sort of magnetic resistant metal.

 yah, ive heard of megnetic forces being able to deflect other magnetic forces before. not completely canceling them out like i said before, but deflecting the effects of them.

I do like how his armor stood against Thor's lightening.. but nothing stands long against the hammer :)

And the Magneto's deal much like the Sentinals he probably has a suit composed of non-magnetic material just for that. After all he has suits to fight Thor and Hulk, so why not one of hte most powerful mutants in the U

Zero Point energy force field and safe-guards against chaos magic (than can disassemble all complex tools). Electricity shouldn't be a big problem seeing as how he can recharge using it. Mind you he has had problems with electro-magnetic radiation.
