In the entry for Magnetism, it says that it does Kinetic damage (it doesn't specify, but I would imagine it would be Blunt rather than Sharp, most of the time).
But the list of Damage Types on the GM Screen (which is really handy, btw) shows it as Energy/Electromagnetic.
V&V GM and player since 1982, my current campaign is 29 years old
I would treat it as sharp, but maybe vs forms of Protection it should count as Energy>Electromagnetic.
@Majestic The type of damage depends upon the shape of the metallic object being manipulated by the character. If it's a blunt object, say a car, then it's Blunt Kinetic. If it's a sharp metallic object then the damage type is Sharp Kinetic.
I'm guessing the GM Screen has a typo if it says that it is Energy/Electromagnetic... but, of course, I could be wrong.
Hope that helps.
I mean to say blunt. @majestic are you referring to the strike/crush vs metallic targets?
bkadams is correct. Sorry for the typo!
