Even after studying the subject for centuries, scientists are still not entirely sure exactly how the principle of magnetism works. However, they do know that magnetism is a reliable and certain phenomenon, and that it has a clear connection with energy – specifically with electrical energy.
If a piece of non-magnetic metal is wound in wire and an electrical current is passed through the wire for several minutes, the metal will have strong magnetic properties when the electrical current is switched off and removed from the wire. Physicists believe that this could be because the atoms of the metal are rearranged by the flow of electricity, but whatever the explanation, the fact that a fairly ordinary bar can be made strongly magnetic at will is very interesting.
Even more interesting is the fact that magnetism is not a principle that is only related to metals. The Earth itself is a magnetic planet, having both a North and South pole as its polarities. Tissue paper which is rubbed against wool for a sufficient amount of time (usually ten seconds or more) becomes charged with static electricity and immediately demonstrates the ability to attract itself to other non-metallic items.
If the passing of an electrical charge around a plain bar of metal can give it strong magnetic qualities, and the generation of a static electrical charge can make even tissue paper attract itself to other objects, then it stands to reason that anything carrying an electrical charge will show some magnetic qualities. And the incredible thing is that everything in the physical universe carries at least some level of electrical charge… even the human body!
The human body is a hive of electrical activity, because every single cell in the human body actually generates its own electricity. Information is carried around the central nervous system via electrical impulses. Of course, the brain is a particularly active part of the body from an electrical point of view, and thinking can have a direct influence on how electrically active it is. In fact, on the physical level alone, it has been said that thoughts are themselves electrical impulses.
So, thought is magnetic because it is basically an electrical process. Knowing this suddenly makes things like non-verbal communication much more understandable, because it means that we should be able to sense the electro-magnetic emanations of other individuals just as easily as we can sense the positively charged ions that are in the air just before a thunderstorm breaks out – and the negative charged ones that follow afterwards.
