In my first post about Magneto I failed to discuss the inventive way he escaped from his plastic prison. His accomplice seduced the prison guard, sedated him, and gave him an injection of some metallic liquid. Magneto then ripped out the metal from the guard and used it to burst out of his jail.
“Magneto uses his powers to lift a security guard from the ground (magnetically) and then kills him by extracting the iron-rich blood from his body (nothing too graphic, but we do see a reddish mist floating through the air plus many tiny bloody spots on the guard’s shirt). He then uses several small metallic balls to smash through his confines and then hit two guards, knocking them to the floor (injuring or killing them).” — Review Site.
Obviously we know that usually humans contain around 4-5 grammes of iron, in molecular form (most famously in the centre of the haemoglobin molecule) — Either this is not enough for an impressive prison escape, or it is not possible for Magneto to manipulate with a magnetic field.
Magneto’s power is to manipulate magnetic fields. With a suitable magnetic field it should be possible to diamagnetically levitate water or, as famously demonstrated, frogs. Perhaps smuggling frogs into the prison would just make a mess rather than smash through the plastic walls.
Perhaps the injection was of metallic clusters large enough to have ferromagnetic properties, if it is possible this could be injected into a body without causing significant damage (anyway the prison guard is going to die). For a ferromagnetic material it’s prefered to have a single domain particle below a certain size, since the domain wall has a certain energy. What the minimum size is for ferromagnetic properties I don’t know… if we assume it requires the free movement of electrons then it could be around 30-50 atoms which has been shown to be a critical amount for metal-nonmetal transition in transition-metal clusters.
It would also be consistent with Magneto only having the ability to manipulate existing magnetic fields, maybe the guard was injected with metal clusters which are already magnetised.
The guard was injected with around 1 litre of liquid, which had a metallic appearance. Around 20 g – 100 g of metal appeared to be formed by magneto by after extracting the iron from the guard.
