Magnetism

Magnetism is vital for Earth and for all the beings on Earth.

Any magnet or electrical conductor creates a magnetic field around it. The effect of the force is transmitted between the magnets through the magnetic field. The magnetic field is also present if there is no other magnet nearby. The sources of magnetic forces are represented by the poles of the magnet. The magnet is bipolar. The north and south poles are preserved, the magnetic field cannot be unipolar, unlike the electric field which can be negative or positive. 

The magnetic field can be characterized by magnetic induction (magnetic flux density). The magnetosphere functions as a protective shield against the solar wind, diverting these rays towards the poles on spiral paths. The most well-known phenomenon of this protective membrane is the aurora borealis which is visible near the North Pole and now, recently, also in the Southern Hemisphere. 

Only the magnetic field is able to protect us against the harmful effects of the Sun. Without a magnetic field there is no life on Earth. Humans lose 80% of bone calcium if they spend a long time away from the Earth's magnetic field. The Earth's magnetic field is able to reverse and then life forms disappear for a while. 

The last reversal took place 500,000 years ago and lasted 10,000 years. Other reversals occurred 2.5 million years ago and 3.5 million years ago. The strength of the Earth's magnetic field is decreasing. For example, 4000 years ago the Earth's magnetism was 4.0 Gauss and today it is 0.47 Gauss.

In the opinion of many researchers, numerous diseases are caused by the decrease of the Earth's magnetic field: allergies, headaches, joint pains, circulatory problems, depression and many symptoms: dizziness, drowsiness, stiff shoulders, back, chest and neck pain, etc. At the level of cells, living organisms are based on physico-chemical and biological processes whose perfect harmony is indispensable for maintaining health. 

 The magnetic field of the globe influences these processes exerting an effect on all the processes that take place at the level of molecules. Health problems are caused not only by the decrease in the magnetic field, but also by the fact that most of our time is spent in buildings made of concrete, metal and artificial substances and cars made of metal and plastic, which is combined with electrical pollution from Wi-Fi devices and wireless that generates a low-frequency electromagnetic field. 

The first electromagnets were created in 1830 by Joseph Henry and William Sturgeon and together with Michael Faraday and J.C. Maxwell who theoretically explained the formation of electromagnetic fields, it was possible to start a modern chapter in the history of the magnet. Magnetotherapy developed after the second world war. 

Diagnostic magnetic resonance devices were invented in the 1970s and even pulsating magnetic therapy (PEMF) healing devices in the 2000s. For their functioning, cells need energy. Cells are able to produce this energy through their own metabolic processes. They need nutrients and oxygen. The reception of nutrients and the elimination of waste are ensured by the electrical potential of the cell membranes.

The modified membrane potential in the case of illness can be restored by pulsed magnetotherapy because it is able to activate voltage-dependent membrane channels and the functioning of other membrane components, accelerating the metabolism process of all cells.
