👉 A flux is a measure of how much an object or system transfers energy and momentum from one point to another. Fluxes can be classified into two main types: total flux (flux per unit area) and partial flux (flux per unit volume). In physics, fluxes are often used in the context of electric fields and magnetic fields, where they represent the rate at which a charge or current passes through a certain surface. For example, if we have a conductor that carries an electric field, then
