Electric motors came to fruition due to the invention of the battery (A. Volta, 1800), the electro magnet (W. Sturgeon, 1825) and the discovery of a magnetic field from electric current (H. C. Oersted, 1820).
The first working rotating electric motor was introduced in May 1834 by Moritz Jacobi. In 1838, Jacobi reintroduced an improved and more powerful motor.
