Secondly, if there is a magnetic field in the living room, people's influence will not be too great under dynamic conditions, but it will be greater under static conditions.
Magnetic field belongs to electromagnetic radiation. Although it has a long wavelength, it also has a certain amount of energy. Nuclear magnetic vibration belongs to an experimental technology that uses electromagnetic radiation in this band to achieve detection purposes. What it can cause is the spin motion of the nucleus. So I always think it should be harmful.
I have consulted several nuclear magnetic experts at home and abroad, especially the foreign professionals in Varian, who always ask questions when they visit each year. The answer they have got for so many years is "no impact".
I care so much because I think it doesn't work, but my family has always been wary of fear, especially when my wife was pregnant a few years ago.
People who do MRI say it's nothing, but it's better for pregnant women to be less exposed to electromagnetic fields. Because the so-called no effect is because the shielding effect of the machine is better, it does not mean that the magnetic field is harmless to the human body. For 300MHz instruments, you can do super shielding inside the magnet; But for high-field instruments, the 5 gauss line is still outside the magnet. Moreover, the super shield is horizontal, so it is inevitable to remove the magnet when changing the probe for tuning.
Changes of blood properties under (1) strong magnetic field and its influence on the body. The orientation behavior of human and animal whole blood under strong magnetic field and the action mechanism of main red blood cells have been studied internationally. Changes of blood rheological characteristics under strong magnetic field: changes of blood fibrin activity under strong magnetic field and its influence on biological metabolism: magnetic force, magnetic levitation and light absorption characteristics of human blood under strong magnetic field.
(2) The characteristics and application of protein polymer under strong magnetic field. The orientation of peptides in phospholipids under strong magnetic field has been studied internationally. Phosphorus metabolism of muscle cell protein in magnetic field: structural changes of neuropeptide amino acids and exchange of protein amide and hydrogen under strong magnetic field.
(3) Medical application. In addition to the development of human imaging system, in recent years, the activity of blood fibrin under 4-8 Tesla strong magnetic field and its influence on intravascular thrombolysis have been studied internationally. The influence of strong magnetic field and magnetic field gradient on cellulose dissolution process: the activity of strong magnetic field on animal blood cells and its influence on myocardial protection characteristics; the influence of external magnetic field on platelet fluidity and its application in medical treatment.
