In 1882 Tesla discovered the Rotating Magnetic Field - - a Fundamental principal in physics and one of the greatest discoveries of all time.
In 1887 Tesla registered his patent for electro-magnetic motors; subsequently, 40 patents followed. These patents were related to polyphase systems, motors, generators, distribution and transmission of electricity.
In 1888 George Westinghouse bought the 40 Tesla patents. Those 40 patents were applied in 1891 at the Hydro-electric power plant at Niagara Falls.
In 1896 Niagara Falls power plant began to operate. It was immediately recognized as the electrical wonder of the world.
Tesla's polyphase alternating system electrified the world and sprung the industrial revolution world-wide at the turn of the century.
In 1891 Tesla invented a transformer for the production of high frequency and high voltage electricity known as the Tesla coil. Today, the Tesla coil is used in every television and radio produced, as well as in many other applications.
In 1898 he took out a patent dealing with the remote control by radio of moving vessels and vehicles. By this invention he laid the basis for wireless telemechanics, robotics and satellite communications. Tesla patented this invention in 10 countries.
Nikola Tesla patented the basic system of radio in 1896 (the four tuned circuits system). His published schematic diagrams described all the basic elements of the radio transmitter which was later used by Marconi.
The United States Supreme Court in June 1943 held Marconi's most important patents invalid, recognizing Tesla's more significant contributions as the inventor of the radio.
The patents followed in the field of turbines, pumps, fluids, lightning protectors, flow-meters, speed indicators, etc.
The last 2 patents for which Tesla applied in 1921 and 1927 were in the domain of avionics.
Tesla's patents were registered in 25 countries, mostly in the US and England.
Over 700 patents were issued to Tesla worldwide.
