Nikola Tesla conceives the rotating magnetic field principle in Budapest (1882)

Nikola Tesla, a Serbian-American engineer, claimed to have conceived the rotating magnetic field principle in 1882 while working in Budapest. This retrospective assertion predates his 1887 induction motor development. The principle involves polyphase currents generating a rotating field, which Tesla later utilized in his motor designs, though the specific Budapest park episode lacks direct source confirmation.

Background and detail

Background. Tesla moved to Budapest in 1881 to work at the Budapest Telephone Exchange. In 1882, he secured a position in Paris with the Continental Edison Company. The rotating magnetic field is defined as the resultant field produced by coils supplied with polyphase currents, a concept central to induction motors and generators.

Conceptual Claim. Tesla claimed to have conceived the rotating magnetic field principle in 1882. This idea was later applied in his 1887 induction motor, which used polyphase current to generate a rotating magnetic field. The principle was also explored by Galileo Ferraris, whose work influenced patent considerations by Westinghouse.

Technical Context. Rotating magnetic fields are utilized in electromechanical applications like induction motors. The field can be produced by poly-phase currents or single-phase currents with out-of-phase windings. Tesla attempted unsuccessful designs in the early 1880s before building a working prototype in 1887, relying on the principle he claimed to have conceived earlier.
