Okay zu, for the sake of discussing the topic I will attempt to prove to zu that the characters did indeed have iron in thier blood. First of all I am assuming they are humans like us and that they have the same basic genetic make up and nutritional needs. They need iron to carry oxygen around the body, ensure a healthy immune system, and to make energy. Then again I could be entirely wrong, they are in a fantasy world where fantastic things happen. But here's a rational solution I came up with. The magnetic field is strong but not strong enough to make it to where the iron in thier blood would be sucked out or to where the characters couldn't pull their swords at a walking pace. That is why they can't fight with them because they can't swing them fast enough. I hope this clears everything up and isn't considered a rammble.
