The electromagnetic fields have a great influence on the behavior of all the living systems. The human body itself is a source of naturally generated electric and magnetic fields. When external signals of comparable strength flows through the human body; the nature of changes that such signals could induce in natural electrochemical processes and voltage is a subject of interest and of considerable biomedical research. When analyzing the interaction between the electromagnetic fields and human body, two main objectives can be identified. First of all electromagnetic fields can be considered as harmful to the health. Using the results of epidemiological studies and by application of the ALARA (As Low As Reasonably Achievable) principle, the governments have imposed some limitations to the authorized radiated fields by the power systems. Secondly the electromagnetic fields can have very positive properties for medical treatment and for medical diagnosis of some health problems. As example, hyperthermia is used in oncology treatment to treat localized cancerous tumor.
