Today Doodle is about Tesla.

So what is Tesla?

The tesla (symbol T) is the SI derived unit of magnetic flux density (which is also known as “magnetic field strength” and “magnetic induction”). (Commonly, the symbol B is used for magnetic flux density, but this is not necessarily true.) One tesla is equal to one weber per square meter, and it was defined in 1960^[1] in honor of the Serbian-American inventor, physicist, and electrical engineer Nikola Tesla. One billionth of a tesla is a nanotesla, equivalent to 0.01 mG or 0.01 milligauss, and it is in nanoteslas that common metric home measurements are made to determine local magnetic field levels.

Who is Nikola Tesla?

Nikola Tesla (10 July 1856 – 7 January 1943) was an inventor and a mechanical andelectrical engineer. Tesla was an ethnic Serb born in the village of Smiljan, Vojna Krajina, in the territory of today’s Croatia. He was a subject of the Austrian Empire by birth and later became an American citizen.^[2] Tesla is often described as an important scientist and inventor of the modern age, a man who “shed light over the face of Earth”.^[3] He is best known for many revolutionary contributions in the field of electricity and magnetism in the late 19th and early 20th centuries. Tesla’s patents and theoretical work formed the basis of modernalternating current electric power (AC) systems, including the polyphase power distributionsystems and the AC motor, with which he helped usher in the Second Industrial Revolution.
