I've seen it two different ways: way back in "New Mutants," he could affect the shield, but in an early "Avengers" he couldn't affect the Shield (even though he could manipulate Thor's hammer).
Nope, Molecule Man had a hard time messing with its molecules and MM >>>> Magneto.

Dan Jurgens:This is a perfect example of why I don't make it a habit to frequent these boards. Any implication that I'm backtracking here to cover my behind is wrong.
I meant only to clarify a statement. I do not believe Superman is a million times stronger than Thor. I do not see how anyone in their right mind could think so.
also, the beyonder stated that out of all these items: mjolnir, surfer's board, iron man's suit, and cap's shield, the shield was the most amazing atomic structure (or something to that effect) when he remade them after he destroyed them. most likely cap's shield isn't just a notch more durable than adamantium is, it's probably far more than that.

his powers are not limited to what knowledge is currently available to man on science. If a substance exists and is not protected by magic: Juggs or mutant energy: forcefields, invulnerability, hf, molecular control... then Magneto can tear it apart like adamantium.
Reed, Forge, The Black Panther Magneto and Apocalypse could hold off Cap and wreck the shield with a science based attack.
Apocalypse probably wouldn't need to know the finer details of how he did it
Magnetos powers are still limited.... To magnetism... So your saying that magneto would be able to affect pure h2o that was stilled and has no mineral deposits...
