Discussion Overview

The discussion revolves around the fictional character Magneto from the Marvel universe and the plausibility of his ability to control metal and non-magnetic objects through magnetic fields. Participants explore the theoretical implications of such powers, touching on concepts of magnetism, energy conservation, and potential real-world applications.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that Magneto could theoretically control metal through a push-pull mechanism, but question the feasibility of altering mass to avoid repulsion.
  • Others argue that his abilities are purely fictional, as he can create magnetic fields of arbitrary strength without regard for physical laws.
  • A participant suggests rephrasing the question to consider how someone might plausibly have similar abilities, referencing the use of prosthetic devices controlled by electromagnets.
  • Concerns are raised about energy conservation issues related to Magneto's powers.
  • Some participants note that Magneto appears to manipulate all types of metal, not just magnetic ones, and question the strength of forces he applies, citing examples like stopping bullets.

Areas of Agreement / Disagreement

Participants generally agree that Magneto's abilities are fantastical and not grounded in real-world physics. However, there are competing views on the nature of his powers and the implications of magnetism, leading to an unresolved discussion about the plausibility of similar abilities in reality.

Contextual Notes

Limitations include the speculative nature of the discussion, reliance on fictional premises, and the lack of consensus on the mechanics of magnetism as applied to non-magnetic objects.

He seems to move metal around freely. I could imagine that he could do a push pull type of action, but that's about it. Even then, he would need to be able to alter his mass to avoid being repelled.

Is it at all possible that a source of magnetic fields freely controls the field lines in such a way to completely determine the trajectory of magnetized objects at a location far away?

How would he work? He wouldn't. He works in the marvel universe because he can create magnetic fields of arbitrary strength anywhere within his vicinity.

Yeah, there are definitely energy conservation issues.
 
I know the answer is "it's fantasy" but I like these types of questions. I think we can rephrase it to ask how somebody might plausibly have a similar ability.

We do have prosthetic devices now which people can learn to control (more or less) like a normal functioning appendage. What if, instead of a hand that opened/closed and grabbed stuff, we equipped a person with an electromagnet whose strength they could control in a similar fashion?

I have no idea why we would do it or what the advantage would be.

Well, in the world of sci-fic magic, sure. That's exactly what he does, AND he does it without any corresponding reaction on his body. In the real world, this is just silly.
 
I always assumed it had nothing to do with magnetism. He seems to be able to manipulate all metal, not just magnetic ones. He also seems able to apply forces that are far too strong for magnetism. Hasn't he stopped bullets in their tracks? Those are very small, very fast, and not magnetic.

Since it's all just magic anyway I hadn't really thought about it but those are excellent points.
