Iron is attracted by magnets.But what about the iron in our blood?Do the force has any effects on us

Do you ever wonder that if we handled a strong magnet (#monster_magnet) what happens to our body.

Let’s check it out how our blood vessels react to a strong magnet and why it acts so strangely.

Usually if we figure out then, we can realize that when our blood is exposed to magnet then the iron in the blood should clo t near the in your blood vessels. This causes a severe pain. But luckily the iron is not in its normal form in our blood. Instead it is a part of a big molecule “the metalloprotien hemoglobin”.

Hemoglobin is the red part in our blood and responsible for transportation of gases within our body. If we write down the chemical formula of hemoglobin (C2952 H4664 O832 N812 S8 Fe4) we can see that the complex has 4 iron atoms. Now you can understand why I was talking about strong magnet. The conclusion of this question will take us to the quantum-mechanical effect, although it does not compute well with our every day logic. But in a very simplified manner, magnetism is a interaction between unpaired electron moving in the materials. Paired electrons will sort of cancelling out their magnetic dipole moment by having opposite spins in the atom and molecule. So roughly we can calculate the magnetic reaction of an atom, molecule or crystalline structure by determining the number of unpaired electron in it.

In hemoglobin number of unpaired electron depends upon whether the molecule is oxygenated or not.

Each iron atom in a deoxygenated hemoglobin has 4 unpaired electrons making it paramagnetic and little attracted to magnets. Each iron atom in a oxygenated hemoglobin has zero unpaired electrons. It gives the hemoglobin a diamagnetic nature. Diamagnetic molecules are repelled when placed in a strong magnetic field. Hence hemoglobin is repelled despite of having iron in it. The ratio of oxygenated and deoxygenated hemoglobin is approximately 1. Areal blood 96-99% oxygenated; 1-4% deoxygenated 2. Venous blood 60-80% oxygenated; 20-40% deoxygenated

Most of the hemoglobin in our blood is in diamagnetic state which is repelled by magnets. Moreover the water which makes half of the blood is also diamagnetic. So after all it makes sense that the blood should be repelled by the magnet.

But there is no need to worry about because the diamagnetic nature is feebly repelled by the magnets. The force is very small. But it would have been a problem if the nature of the iron is ferromagnetic. Ferromagnetic things are strongly attracted or repelled by magnets. Lastly there is no reason to worry about the iron in our blood. Even the strongest magnets – like the superconducting electromagnets in the MRI scanners will not be a problem.

I hope you learnt something new from this article
