🔬Iron in our blood is not in the form of solid metallic pieces but is part of a complex molecule called hemoglobin.
💉The iron atoms in deoxygenated hemoglobin have unpaired electrons, making it paramagnetic.
🧲The iron atoms in oxygenated hemoglobin have paired electrons, resulting in a diamagnetic reaction and causing the blood to be repelled by magnets.
💡The magnetic properties of atoms, molecules, and crystalline structures are determined by the number of unpaired electrons.
❓The ratio of oxygenated to deoxygenated hemoglobin in our blood is typically such that most of our blood is in the diamagnetic, repelled state near magnets.
