This system differs from the transformer as both the primary and the secondary circuit are in resonance with the operating frequency. Later, his invention became an essential component of numerous devices. Tesla coils produce spectacular phenomena in the form of high-voltage corona discharge which also depend on the top load attached to the secondary coil. He built the prototype in , while working in France.
He patented his invention, a motor driven by a rotating magnetic field , in the US in Alternating current is electrical current with periodically changing direction and intensity. The stator consists of several coils that are fed by an alternating current. The rotor can be a simple metal cylinder , but it usually also contains a coil.
The alternating current flowing in the coils of the stator generates a rotating magnetic field around these coils.
This rotating magnetic field induces electric current in the coil of the rotor. The induced electric current generates another magnetic field around the coil of the rotor. Due to the magnetic field generated around the coil of the rotor, the north pole of the rotor tries to turn towards the south pole of the magnetic field of the stator. However, since the rotating magnetic field keeps changing around the coils of the stator, the two poles never align , and the rotor revolves constantly.
A rotating magnetic field is generated only when the coils of the stator do not work at the same time but at different phases. If polyphase power is used to drive the motor , the coils of the stator must be fed with different phases of current for a rotating magnetic field to be generated. When the motor is driven by single-phase power, the external coils cannot operate in the same phase, because no magnetic field would be produced.
The motor will not start unless there is some phase difference, but if we help the motor start, it will rotate without the need of phase difference. Tesla was an advocate of the alternating current while Edison was a strong supporter of the direct current. Not only his contemporary demonstrations , but also history has proven Tesla right. Today, numerous devices work on the same principle as his AC motor. The birth of the theory of radio and the invention of the device itself paved the way for the development of other areas of wireless transmission.
He controlled a boat with a remote control he had patented in that used radio waves. Despite the myth surrounding the light tube , it was not Tesla who actually invented it. However, in the s he worked with light tubes that were powered by high-frequency power sources. This is how he described the reception of his light tubes: "When my tubes were first publicly exhibited , they were viewed with amazement impossible to describe.
In Nikola Tesla unveiled his invention, the so-called Egg of Columbus. Legend has it that Christopher Columbus made an egg stand on its end by tapping it on the table thereby causing great amusement among the audience, hence the name. The basis of the device was an iron ring stator - stationary part which was linked to four coils electromagnets. The copper egg was spinning on a wooden platform. An alternating current source was responsible for creating the appropriate magnetic field.
The turbine Nikola Tesla patented in was a very simple, but highly effective device. The bladeless turbine consisted of parallel discs and its operation was based on centripetal flow. It also worked with gas and fluid. The flow of gas or fluid turned the shaft. The outlet was located at the bottom of the turbine. By changing the direction of the rotary motion, it could also be operated as a pump. Nikola Tesla said the following of his invention: "In my invention practically the whole surface is active.
In the bucket turbine the action does not even extend all the way around; you must have a series of jets. But in my turbine you have the gas traveling all the way around in free spirals —always seeking the path of least resistance—and expending its full energy. Even though the turbine was relatively cheap to construct and highly effective, it never became widespread.
Legend has it that on his deathbed, Tesla described the turbine as his most important invention. Nevertheless, the device has become as good as forgotten. One of the most brilliant figures in the second industrial revolution, Nikola Tesla became one of the greatest inventors of all time with patents to his name. He was very gifted even as a teenager and made good use of his skills later as an engineer and inventor. He travelled all over Europe as a service engineer before moving to the US in to work with Thomas Edison.
He spent his best years as an inventor there.

Office Hours - By appointment only Mon — Fri, 9am to 5pm Within the next two decades, Tesla, working with Westinghouse and independently as an inventor, made a mark on the scientific community and in the public imagination.
His experiments with electricity resulted in the invention of the Alternating Current AC that we use today. He was a pioneer in X-ray technology, remote control, and wireless communication. In , he lost the heavily mortgaged property in his attempts to cover his debts.
