### Description

Both in A treatise on electricity and magnetism (1873, 2 vols.) and A dynamical theory of the electromagnetic field (1864) Maxwell converted in a mathematical language the main content of the Experimental Researchers in Electricity by Michael Faraday. He went beyond the Newtonian approach reaching a new physics mathematics based on the concept of energy instead of that of force. First, he mathematically stressed the three – as he called – Lagrange’s methods and then used Lagrangian formulating through the idea of connected mechanical system described by means of Lagrange’s […] equations of motion of a connected system. In our talk, the first part of the Lagrangian and its specific formulation adopted by Maxwell are discussed.
