Nikola Tesla... 153 years of magnetic flux towards WLAN

Nikola Tesla (1856-1943) was the genius who lit the world, whose discoveries in the field of alternating polyphase current electricity advanced the world into the modern industrial era. Nikola Tesla had 700 patents in the US and Europe. Tesla's discoveries include the Tesla Coil, fluorescent light,Tesla Statue wireless transmission of electrical energy, radio, remote control, discovery of cosmic radio waves and use of ionosphere for scientific purposes. Nikola Tesla was a New Yorker, who lived and worked in New York City almost 60 years and died at Hotel New Yorker, in Manhattan, on January 7, 1943

Tesla is the father of high frequency, high voltage electricity which is used today in radio and other communication devices as WLAN. WLAN acronym for wireless local-area network. Also referred to as LAWN. A type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes.

Tesla = Weber/m²
Nikola Tesla's name has been honored with the international unit of magnetic flux density called "Tesla".
All magnetic resonance imaging (MRI) machines are calibrated with Tesla Unit (from .2 Tesla to 9 Tesla). MRI machines work on the principle of a homogeneous magnet field. Nikola Tesla discovered the Rotating Magnetic Field in Budapest, 1882. The Tesla Unit for magnetism was established in 1956 in the Rathaus of Munich, Germany by the International Electrotechnical Commission Committee in Action.
Because of the tremendous importance of the MRI technology and widespread use of the MRI machines around the world, which are all calibrated in Tesla Units, Tesla's name connected with the MRI will be known more and more in the future and the years to come.
Magnetic Resonance Imaging (MRI) is extremely important for medical diagnosis of internal organs of the human body, especially the diagnosis of cancer, tumors, degenerative diseases of the brain and spinal cord. The modern diagnosis of the internal organs of the human body would be today unthinkable without MRI. MRI machines are widespread with many variations in size and capacity all around the world. The revenue of MRI machines sales was 1.46 billion dollars in 2002. Revenue for MRI machine sales is expected to increase in the following years.
MRI employs a strong homogeneous magnetic field and specific radio frequency to which many elements, especially hydrogen nuclei respond with radio frequency signals. These signals are analyzed by computer reconstruction algorithms. The healthy tissue and pathological tissue have different radio frequency signals and produce different images on MRI. Therefore enable us to make diagnosis of pathological tissues of the body.
MRI has the advantage over CT scan, it uses no ionizing radiation and does not cause cumulative harm. The only contraindication of those related to the high magnetic field. Magnetic-sensitive objects like pacemakers, watched and magnetic tapes are contraindicated.
