Fluid-dynamic formulation of Maxwell's equations

Many phenomena in electricity and magnetism have been storically interpreted using fluid-dynamic analogies, e.g., electricity was seen like a fluid #x201C;current #x201D; of some kind. J. C. Maxwell himself interpreted magnetic field as originated by vortex of (electric) current and electromagnetic waves were considered travelling through an elastic fluid called #x201C;aether #x201D;[1]. At the end of XIX century researchers in Fluid-dynamics and Electromagnetism began to separate their objectives, developing different methods and notations and nowadays their fields looks quite distant.
