The term electromagnetism refers to magnetic forces which occur under the influence of electricity. Electromagnetic devices may be easily used to produce magnetism varying in intensity and direction. This is a relatively new application of magnetic force, but this force is all-pervading and has the same effect on the human body as do natural magnetic forces.
Various magnetic materials
Different materials have different properties which enable them to become magnets. There are four types of modern magnets for wide use. Each of them is based on a different material structure. Among each of the types there is an indicator of intensity which is used for determining the intensity of the magnet, i.e. there are potent, middle ranged and weak magnets. Each of them has characteristic properties. Four types of magnets are magnets made by combining neodymium, iron and boron; the combination of samarium and cobalt; magnets made of ferrite and alnico magnets. The first two kinds are also known as rare element magnets because they occur as a combination of elements which are rarely found in nature. Magnets made of the combination of neodymium, iron and boron are a recent addition to the collection of modern magnetic materials.
Ferrite magnets or ceramic magnets were developed in the fifties and are still in use. The special version of this magnet is the ‘flexible’ magnet obtained by spreading ferrite powder along some flexible material such as rubber or fabric. Alnico magnets were made in the thirties and are still in use.
Magnet rubber is obtained by sprinkling ferrite powder based on barium and strontium on a rubber or PVC matrix and is then molded and cut into strips. Material prepared in this way is usually subsequently magnetized. Most rubber magnets are flexible.
How magnets affect our body
Magnets create order among the chaotic molecules of a matter, in this way they enable molecules to travel through tight vessels; this has an important application in the human body.
We can compare the flow of molecules through blood vessels to the floating of a tree trunk down a river. If the trunks are aligned they will move along the entire flow and reach the destination. But if they are not aligned they move sideways together with other trunks and block the flow. Magnets ensure that all the molecules are arranged accordingly, in a line, as trunks floating down a river. The same illustration may be used for energy flows in the body because chaos makes obstructions and order accelerates the flow.
Research has shown that magnets increase the production of amino acids and positively affect the entire body. In other words, magnets accelerate the metabolism and help the body function properly. They help oxygen and nutrients arrive at the location of injury as soon as possible so as to repair the damage.
Water accounts for 66% of our body. Magnets weaken the surface tension of water. In this way all substances transported by water can be transferred more easily into the cells that need them. Hemoglobin, the substance carried by red blood cells, contains iron which binds oxygen and transports it to where it is necessary. If molecules of iron are properly arranged they accumulate the energy which improves blood. Furthermore, magnets affect the molecules in the body even though they do not come into contact with them. This means that a properly positioned magnet can affect the cells and bodily fluids through the skin so that it is not necessary to perform skin puncture.
