Can't remember what was going on with Magneto here. Isn't this when he took the Super Soldier serum and during this fight it had a lasting affect.

By the way, Juggernaut beats him here.
That from, "What If? Kindgom of Cain". When Mags could no longer hold his shield, he succumbed to the radiation that was a result of all the Sentinels. In that comic, the radiation killed, almost, everyone on Earth. Juggs power made him immune and Magneto's shield kept him safe. There was an underground society shielded from the radiation, but when Cain entered the area, he broke the barrier keeping them safe. Eventually they all died which left Cain to wander the Earth alone.

Magneto can't manipulate his armor, so he can't toss him anywhere. The only Juggernaut he ever tossed was the one made of metal.
Why can't he target the iron in Juggernaut's blood and toss him into space? Sure, he can't rip the blood out of him like he did to that one guy in the movies, but then he doesn't need to. Also in the movies he needed the guy to have extra iron injected into him, but comic Magneto can do that trick regardless of if you have extra iron in your blood or not.
I also thought at his most broken power levels he had magnetic fields so strong he could manipulate non-metal objects?
