waves are electromagnetic fields of a movement patterns. It can be said that electricity and magnetism are two sides of the same coin, the current will produce a magnetic field, the magnetic field is generated current. Changes in the electric field and magnetic field changes in the f ...
Electric and magnetic fields are ubiquitous in the modern society, and concerns have been expressed regarding possible adverse effects of these exposures. This review covers epidemiologic research on health effects of exposures to static, extremely low-frequency (ELF), and radio frequency (RF) fields...
However, as proved in, e.g., [2] ([2] T. Ivezi\\'c, Found. Phys. Lett. 18, 301 (2005)), these transformations drastically differ from the LT of the relativistically correct 4D electric and magnetic fields. In this paper a simple proof of that difference will be presented and ...
Power frequency magnetic fields have been implicated in SIDS. Through the use of a case-control study measuring 50 Hz electric and magnetic fields at the SIDS baby's last head position, no association could be found between SIDS and either electric (p = 0.327) or magnetic (p = 0.827) ...
