Question: As seen in this screencap, Magneto seems to be pulling Mystique towards him using his powers. What I don't understand is, **how** can Magneto affect Mystique? Since when did he gain the ability to manipulate human beings using his powers? Or is there anything unique about Mystique that makes her vulnerable to this? Any comic references to this?

Answer: 
**For clarity the answer below is a pre-release trailer based answer**

There are many possible answers to this question you will not find out for certain until you watch the film.

1. Something she is wearing, he is not pulling her but pulling something she has on.
2. Like stated in the comments it's the iron in her blood that he is pulling.
3. She is holding onto something that he wants and he is dragging her as a result.

He can't affect her directly, he would have had this power in the future if he had gained it in the past. He still only has the power to influence metal in the future though.

I doubt it, there has never been anything mentioned about Mystiques powers other than her transformations.

Not that I can recall although I'm not one of the more prominent comic aficionados of the site.

After re-watching the trailer it looks more and more like there is something on her ankle just due to the way in which her leg is raised, she is also clearly not holding anything.
She had been shot before. The bullet in her leg is his 'leverage'.
