# Could you make someone magnetic without killing them? [closed]

Edit: having read some (very helpful) responses, I now think my question is closer to this: Could you, either by somehow distributing a foreign substance throughout someone's body, or by somehow causing them to generate an electric current, cause them to have a magnetic field around them such that a key would stick to them? And could you do it without killing them?

It is a highly speculative, and pretty dumb question, but I am curious.

• No, there is not. Lack of ferromagnetic domains in most materials. Water is paramagnetic but this is much much weaker that ferromagnetism that you see when something like a magnet sticks to a fridge. It takes an MRI machine just to elicit a response and even that won't have a visible or feelable attraction. Sep 12 at 2:26
• a subcutaneous iron implant would do it, though. Sep 12 at 3:02
• If you charged the human and shot an iron key past them at high velocity, the key would deflect towards them. Does that count?

Even if vaccines did contain magnetic materials, there certainly would never be enough to "make a person magnetic". There is less than a milliliter ($$\lt 0.3$$ milligrams I think) of material that is injected via the syringe, some of it, it is alleged by those who push this idea, is magnetic. But still this is nowhere near enough to create an even hardly detectable magnetic field. Think about the fact that on average, an adult human already has approximately $$3-4$$ grams (not milligrams, actual grams) of iron in their body. This on its own is $$10,000$$ times more than if the entire volume of the vaccine was a magnetic substance.
