Rotating Magnetic Field : Tesla's first breakthrough came when a professor in his native Croatia he was ethnically Serbian told him it was impossible to create a motor powered by alternating current AC instead of direct current DC. Tesla was sure this wasn't the case, and after two years of performing experiments in his mind, the solution came to him like a bolt of lightning: a rotating magnetic field that would allow alternating current to power an engine without being first converted to direct current.
AC Motor : Tesla carried detailed plans for this AC motor in his head a particular talent of his until he could build a physical model the next year. The alternating current created magnetic poles that reversed themselves without mechanical aid, as DC motors required, and caused an armature the revolving part of any electromechanical device to whirl around the motor. This was his rotating magnetic field put into practice as a motor; within two years, he would use it in AC generators and transformers as well.
Tesla coil : The electrical coil named for its inventor is one of Tesla's showiest inventions, and he used it to its full dramatic extent in demonstrations held in his New York City lab. The coil uses polyphase alternating currents -- another of Tesla's discoveries -- to create a transformer capable of producing very high voltages.
It brought forth impressive crackling sparks and sheets of electric flame that impressed the electrically savvy and the layman alike. They're primarily used for entertainment today.
Radio : Tesla first sent a wireless transmission from his lab at Houston Street in New York City to a boat on the Hudson River -- 25 miles 40 km away -- in ; he would've done this sooner but for a fire that destroyed his previous lab in The magnifying transmitter was 52 feet in diameter and had three coils.
It generated millions of volts of electricity and shot foot-long lightning bolts — the largest man-made lightning at the time. Tesla used radio transmission to power the first radio-controlled toy boat, which used a remote control to regulate its engine, lighting, and steering.
Hydroelectric power was another masterpiece invention by Nikola Tesla. Tesla was chosen by the Niagara Falls Commission to design the hydroelectric power generator at Niagara Falls using his alternating power technology.
That speaks volumes louder about the boundless impact that the inventions of Nikola Tesla had on the people. In , Tesla was preparing to transmit a radio signal over a distance of 50 miles when his laboratory burned down, delaying the test. Most people consider Guglielmo Marconi to be the father of radio, but Tesla is less known for his radio work. All of the earliest patents for the radio, which Tesla invented, were claimed by Marconi. Nonetheless, most of us are still unaware of the fact that it was Nikola Tesla who invented the radio.
This was all about Nikola Tesla, the greatest and most inspiring inventors in the world. Apart from being a successful electrical and mechanical engineer, he was known for the futuristic vision that he had. Want to pursue engineering abroad?
