[Prior Art] With the continuous advancement of science and technology, the external environment in modern life is full of electromagnetic waves of various strengths and weaknesses. When the electromagnetic wave is greater than 2 milligauss, it is likely to cause harm to the human body, and the World Health Organization has polluted electromagnetic radiation. Listed as the world's largest. Electromagnetic waves can cause harm to the human body, including brain tumors, increased blood pressure, vaginal discharge, cancer, leukemia, dementia, and Parkinson's disease. In the future, with the continuous development of electrical and electronic technology, the damage of electromagnetic waves to humans will become more and more serious. Regarding the influence of electromagnetic waves on humans, most of the past research focused on the radiation hazard of high-frequency magnetic fields (such as microwave communication such as base stations and wireless networks), but now through a large number of investigations and studies, it has found that 'low-frequency and extremely low-frequency magnetic fields are harmful ( For example, high-voltage wires, electric towers, transformers, 'substation boxes, motors, generators, etc., which emit low-frequency/very low-frequency magnetic fields are particularly serious. On the one hand, the magnetic field interference generated by low-frequency magnetic fields is an important factor affecting the normal operation of other electrical and electronic equipment. For example, the low frequency magnetic fields generated by the engine can distort the images and readings of the nearby computer display and the communication device. On the other hand, low-frequency magnetic fields can cause the central nervous system of the human body to eclipse and the cardiovascular system, and increase the incidence of leukemia, brain tumors, and cancer.
