At the end of X-Men: First Class, Magneto controls the wires in Sebastian's nuclear reactor room to successfully take off Sebastian's helmet, this allows professor X to freeze Sebastian.
The only problem I have with this scene is that Magneto used the incredibly roundabout method of controlling a wire to remove the helmet when he could have simply removed the helmet directly with his power, and as we saw in X-Men: Days of Future Past, Magneto does in fact have the ability to control this helmet with his powers (as seen when he recovers it from the government that is holding other mutant related objects).
So my question is:
Why did Magneto use the metal wiring to take off Sebastian's helmet when he could have just taken it right off? To be sneaky? Magneto could remove that helmet in a second giving little to no time for Sebastian to react, so the wire just kind of makes no sense to me.
I hope someone can shed some light on this for me.
