<p style='text-align: justify;'>Photograph of Maxwell's apparatus to detect the inertia of an electric current. The objective was to measure the inertia of an electric current as it flowed round a current loop. This was one of three experiments Maxwell performed to detect the inertia associated with the flow of current, none of which showed any evidence for such a phenomenon. These experiments were carried out long before it was understood that electric currents are associated with the flow of electrons.</p>
