I am curious why this does not happen. Why does it not clot, or why does the iron not come to the area where the magnet is?

It IS attracted to a magnet!
The amount of iron in a volume of blood isn't particularly large compared to iron containing materials that you are used to touching with a magnet. The example above, regarding iron fortified foods, is probably appropriate (although I'd be surprised if you could actually extract elemental iron from cereal by "crushing" since the iron isn't in the form of little black metalic chips! - it's molecular and BOUND)
The interesting thing is that iron is only ONE material in the body that is affected by magnetic force. It turns out that many materials have the property of reacting, at least to some extent, to magnetic force.
Because of this property, the technique of magnetic resonance imaging (MRI) is capable of detecting the differences between types of tissues and after scanning a region of the body, displaying them in 2 or 3 dimensions on a computer.
The physics of MRI is extremely complex, however, the basic principle involves orienting particles within the bodily tissues in a powerful magnetic field, and then detecting the energy released as the orientations are relaxed.
Physics is cool, but medicine is even better! ;)

Actually, blood, specifically the component of blood that has iron (hemoglobin) IS attracted by magnetic forces. The reason you cannot easily see this in real life is due to the nature of the material that makes up blood. Whole blood has a viscosity (thickness) that prevents a clear conglomeration of hemoglobin (the iron part of blood) from forming, unless the blood is thinned and possibly placed in a centrifuge.
The same can be said for other 'iron rich' substances. Try dragging a magnet through iron fortified breakfast cereal, and nothing happens. You will not attract iron to the magnet. Crush the cereal into a powder and repeat the experiment, and you will find a big clot of stuff that looks like iron filings on the magnet. Why? The iron content is not bound to larger organic (and thus non-magnetic) material and is free to be attracted to the magnet.

No concept yet taking an informed shot in the ineffective of night right here i could say sure... asserting sure because of the fact although in the liquid/molten type the place the electrons a freely roaming and sliding bypass one yet another in a diverse area, if an electromagnet efficient adequate could be got here across that could nevertheless align those electrons then it is available that even in the molten state Iron could be magnetic

it doesnt have iron , the iron is bound to some other element oxygen, Rost isnt attracted by a magnet

actually ity is because if u have pain u use a magnet and the magnets attraction is used to help ease the pain

well the quantity of iron is pretty much less in blood... thats y...

well i'm not sure, but i think that, too some extent, it is.
