Shielding of Electromagnetic Processes

Hey dear community, first of all I would like to welcome you all to my new post and hope you had a day that brought some positive experiences into your life! Today I would like to deal with a complex topic and hope you are able to expand your knowledge a little.

You can see here pictures of the mineral shungite in different purities and one is a specimen of normal quality and the other one Elite shungite and the levels of the qualities can be mainly attributed to the content of carbon. Elite Shungite usually contains over 90% or more and who would like to know more about the chemical compositions of this normal specimen, which weighs a few kilograms, I have attached a photo in the post at the bottom. One of the most interesting properties of the mineral is to conduct electricity and it is also important to know that shungite helps against electromagentic radiation and can neutralize it and I would like to go into more detail on the complex topic of shielding in this article. It is important to know that the shielding of electromagnetic processes is a complex topic and you must first distinguish from the source of radiation and it is important to distinguish whether you want to shield electric, magnetic or electromagnetic fields and the property as well as chemical structure of the material for shielding plays an essential role. With shungite itself, it is assumed that the carbon contained is one of the reasons for the shielding properties and the conductivity also played an important role and when it comes to the penetration of electromagnetic waves, the conductivity of materials is probably of great importance and you can see this, for example, with metal that has a high conductivity and do not penetrate these waves so easily. Who went into more detail on this topic was Michael Faraday (1791 - 1867) who had found out that when you are in a metal cage, you are well protected from electric waves and due to the conductivity, the waves are distributed evenly on the surface and do not penetrate the interior.

So the material of the shielding is important and of course the frequency of the waves is influential and when it comes to the shielding of magnetic fields the topic looks different again and there these discoveries or a cage made of metal help only a little and to ward off magnetic fields is very difficult in practice and it requires a huge technical effort. Magnetic radiation is extremely persistent when it comes to penetration and that makes a Faraday cage often useless and magnetic fields can even penetrate even thick walls of concrete or steel and only help against electric waves. When it comes to the pure shielding of electric fields, theoretically, a thin layer of metals such as copper is often enough and through several layers of grids it is also possible to shield magnetic fields and this even in larger rooms. Often organic materials are already sufficient to neutralize electric fields and a good example are, for example, plants or the human body and this can also be attributed to electrical conductivity. When it comes to magnetic fields, everything looks different here again because it penetrates deep into the human body and here, too, it is far more difficult to shield the whole thing and is only possible with the right methods.

Thanks for stopping by and I hope you could learn something new about technology! I captured these pictures with my Camera Sony Alpha 6000 plus 55-210 mm lens.
