From history of Electrical Engineering III: Electromagnetism discovery and its fundamental laws in the first half of 19-th century

This paper contains an overview of main findings in electromagnetism started from the Oersted's observation including contributions of A. M. Ampere, M. Faraday, J. Henry, E. Lenz, W. Weber, W. Sturgeon and also fundamental papers of G. Ohm and G. Kirchhoff in theory of electrical networks. All this resulted in the classical Maxwell's electrodynamics background creation.
