The article provides a brief overview of publications and various and contradictory views on the influence of magnetic fields on living organisms and humans. An explanation is sought for findings made in various scientific studies, as well as an answer to the question: Can a permanent magnetic field be useful for our health and under what conditions? Key words: magnetic field, health, diagnostic, physiotherapy, physiological response One of the areas of application of the permanent magnetic field, which is no longer contested, is diagnostic and diagnostic equipment. In a report to the World Health Organization [1], an international panel of experts reported: "The modern generation of magnetic resonance imaging devices used in clinical practice is working with permanent magnetic fields with an intensity of 0.3 to 2 T (3000 to 20,000 G) and RF fields with frequencies up to 100 MHz. Weak spatial gradients around 0.001 T (10 G) are used to determine the tissue location of the MR signal." In our opinion, a crucial point in this report is the finding that even the weak magnetic gradient – 10G – acts on the tissues and this influence is used in modern medical diagnostic apparatuses. A fact that refutes all "scientific" doubts about the ability of a permanent magnetic field, including weak and medium fields, to affect the human body. T. Truong (T. Truong), B.D. Glumer (B. D. Clymer), and others [2] examined the different tissue response in the human head of a mega static magnetic field (8 T = 80,000 G) by three-dimensional digital simulations. The difference in the magnetic sensitivity of cells and tissues, especially when exposed to mega magnetic fields (over 0.5 T), is a valuable mechanism used in magnetic resonance imaging. Brittenham, Farrell, and others [3] make direct non-invasive magnetic measurements of liver iron deposits with a specially designed superconducting quantum device (SQUID) of 20 healthy volunteers and 110 patients with liver disease, iron deficiency, hereditary haemochromatosis or iron overload due to blood transfusion. They combine magnetic in vivo liver iron overload measurements with chemical in vitro measurements in liver biopsy. Through their research, Britton, Farrell and others demonstrate that magnetic measurements of iron depots provide a new quantitative method for early detection of hereditary hemochromatosis and for rapid assessment of liver transfusion treatment regimens due to blood transfusion. And while there is a hopeless consensus that in modern medicine the permanent magnetic field is an inevitable tool and a factor in diagnostics, there is still controversy, often and with no scientific arguments, to what extent the magnetic field is useful for the treatment of various diseases. There are theories that are still trying to question the biological effects of a static magnetic field or its effect on particular subjective symptoms. In the formation of biological effects in magnetic fields, processes from different levels of organization of living organisms are essential, starting with physical processes and ending with complex adaptation biological processes [4]. Experts from different fields analyze the question of the influence of the magnetic field on living organisms from its expert point of view. The medics are exploring organ sensitivity and general physiological processes to the magnetic field. Biologists are looking for cellular and subcellular structures to form biological signals in response to the influence of the magnetic field. Biochemists analyze units of biochemical reactions, the speed of which may depend on the magnetic field parameters. Biophysicists are attempting to emit magneto-sensitive magnetic field interactions with relatively simple molecular structures. It is at this level that complex spectral connections of biochemical processes arise with the biotropic parameters of the magnetic field. Studies on the influence of strong magnetic fields on the human body show significant growth with the development of diagnostic and physiotherapy equipment in medicine and mass influx of mobile phones in everyday life. Over the past 3-4 decades various studies have been conducted to influence strong permanent magnetic fields on laboratory animals. Many of the findings made on this subject have been analyzed in a review by R. Sanders (Saunders) on studies conducted mostly on mammals [5]. Four main areas have been studied: the nervous system, the cardiovascular response, reproduction and development, and
