The Methods Of Protection From Electromagnetic Fields

By Francis Riggs


There are very many substances that make up the planet that we live in. Many of these things are very essential resources while others can be quite dangerous if mishandled in any way. Water is one of the most profound materials on the planet. It is not only found in the numerous water bodies but also underneath the earth crust this element flows freely. The methods of protection from electromagnetic fields are numerous.

Air is another very essential material in nature. Being a mixture of gases, air is made up of gases such as carbon dioxide, oxygen, nitrogen and the rare gases. Carbon dioxide is used for plants in the process of photosynthesis while animals use oxygen for their respiratory needs. Air generally has numerous uses in the community such as sweeping away foul smells and keeping nature fresh at all times.

The plants in the forests also play a very major role in the maintaining the equilibrium of nature. In addition to the provision of food substances these plants also offer shelter to the wild animals and hence keeping them out of the community. Plants also help in the formation of relief rainfall that is very important to the farmers and other people that depend on rain for their water supply.

In the beginning the earth was simply one big rock or at least scientists claim so. This rock was subjected to the numerous corrosive forces in nature and it gradually broke down. This process went on for so long until there were finally fine textured pieces of rocks and these were called soils. Due to the difference in texture and other qualities as well the soils come in various kinds including clay, loamy, sandy soils and others.

Nature is also field with numerous forces that keep everything in equilibrium. One of them is the force of gravity that originates from the moon unto the earth. This force directs all things from the earth back to the earth. It explains why a stone thrown into space finds its way back to the earth within no time irrespective of the amount of strength used.

Finally is a force known as magnetism. This force basically originates from the earth and rotates around the earth from one pole to the other. Other naturally occurring magnets in nature are the lodestone rocks. These rocks posses all the qualities of a magnet as well. They attract other magnetic substances towards them.

These magnets have widely been used in the creation of direction mechanisms. This works due to the fact that the earth is the biggest natural magnet and any other magnet in the force field of the earth will align its diatoms in an opposite polarity to that of the earth. This theory helps navigators to use compass needs to situate the magnetic north and south while at sea.

These magnets were created using electricity and hence were called electromagnets. They have various applications in nature including the lifting of heavy metallic objects in industries, to medical procedures in hospitals. These electromagnetic fields also tend to be harmful if the person is directly exposed to them for a long time. Protective gear has been created for the workers that cannot avoid them.
