Magnetism is an invisible force that is present in our daily life without us noticing, but that doesn’t mean we are not influenced by it. Naturally or artificially, it is present in objects that contain magnets or ferromagnetic materials, including living things.
It was discovered in ancient Greece, because of its presence in a mineral of natural magnetism, called magnetite. One of the first applications of this mineral would be in compasses for maritime navigationbecause it was discovered that the Earth acted like a large magnet, and the terrestrial magnetism always pointed north.
Although that was the beginning of magnetism, its applications have increased and of course, our homes are the best example of this, since almost all the technology around us is based on its force. We can identify several devices we generally use, which have magnets inside or generate magnetic fields, among them are televisions, computers, telephones and radios.
However, this is only a sample of the widespread use of magnetism, as well as magnets and electromagnets, not only in our homes but everywhere else. We can find magnetism in magnetic media and strips in toys, engines, generators, vehicles, handbag clasps, credit cards, electric guitars, among others.
The list seems endless, but perhaps one of its most important applications is health, Because inventions such as MRIs can detect diseases that can be treated in time. Bio magnetism and magnetotherapy can also be used in the treatment of certain conditions such as arthritis, circulatory disorders, stress or pain, among others. In this case, magnetic fields are used on the body. Although its effectiveness has not been scientifically proven, there are people who say it does work.
On the other hand, it is important to know that we interact with magnetism inside our planet, but we cannot live outside of it without its influence. According to studies by NASA, the prolonged absence of attraction to the Earth’s magnetic field can cause us osteoporosis and severe depression. That’s why spacecrafts have artificial magnetic fields to reduce these effects on the health of astronauts.
As you can see, either inside or outside the planet, the development of our life is closely linked to magnetism, so it is almost impossible to escape it. Therefore, it would not be unreasonable to think that with the unstoppable advance of technology, we will certainly have a greater presence of this force in our lives, but hopefully for the benefit of our health and better living conditions.
