Nikola Tesla and His Pioneering Works, 1930 First Issue. The work of Nikola Tesla, Croatian-American inventor and electrical engineer established the basis for the entire industry of modern electrical power. He applied the principle of the rotating magnetic field, which he had conceived, to an induction motor. His first and probably greatest achievement was his discovery of the rotating magnetic field (a magnetic whirlwind produced in a motor winding by the interception of two or more alternating currents) and his adaptation ‘of it to his induction motor and polyphasal system for the generation, transmission, and distribution of electrical power. The combination of this motor and this system provided the first practical means for generating large quantities of electricity of a single type in one place and transmitting it economically over long distances for use at another site. Tesla's other inventions include a system of arc lighting, the Tesla motor, a system of alternating-current transmission, generators of high-frequency currents, a transformer, and wireless systems of communication and of power transmission.
