'''Nikola Tesla''' (July 9, 1856-January 7, 1943) was a Serbian-American electrical engineer, inventor and physicist who contributed to many of the developments in the field of [[electricity]].
He pioneered the eventual adaptation of [[Alternating current|alternating current]], which is more efficient than [[direct current]].
The SI unit measuring magnetic flux density or magnetic induction (commonly known as the magnetic field), is named the tesla, in his honor (see [[induction motor]]).
