Healing magnets are no longer new. It's simple, because today's magnets perform functions in most technical devices that we would not consciously perceive at first, and usually do not at the second glance. Very simple, because they are auxiliary functions, so to speak, so that the related equipment can work and complete its main functions. These may be common things, such as disinfectant dispensers or various measuring devices. But there are also medical applications where magnets are king.
The best example is magnetic resonance imaging (MRI)
One of the most famous examples of the use of magnets in medicine is magnetic resonance tomography. This innovative development was created in the 1970s by the American Paul Lauterbur of the University of Illinois and the British Sir Peter Mansfield of the University of Nottingham. In short, a magnetic field is actually generated around us and an image is assembled based on the body's response, which can then be evaluated accordingly.
Everything is carried out in three stages:
– The disordered miniature magnets in our body are arranged in opposite directions under the action of an external magnetic field.
– The second magnetic field interacts, causing the atomic magnets in our body to absorb energy.
– As soon as the second magnetic field is deactivated again, the energy will be released again, that is, the moment of measurement and assembly recording.
In this way, people can perform detailed inspections without any radiation exposure. However, this is not the only important example where magnets are useful in medicine.
How do medical magnets save lives?
Used for magnetic filtration of diseases such as malaria and leukemia.
George Fordsham, PhD in Biochemical Engineering, has been an innovator under 35 since 2019 because he developed a technology he calls magnetic blood filtration. Here, the use of magnets is also essential. Draw blood from the body to remove toxins and pathogens.
This is a big step forward in the fight against diseases such as malaria and leukemia, because patients are not affected by harmful radiation. His technology, which he calls MediSieve, is still under development. It consists of a disposable filter and magnetic nanoparticles that attach to contaminants in the blood to remove them from the bloodstream. This does not limit the positive substances in the blood.
Developments like this show the potential of using medical magnets.
