Transformers can be represented by paddle wheels and gearboxes and such. They come free with inductance (inertia.) The pedagogical failure of this analogy is how it suggests that the energy is stored in the potential and kinetic energy of the fluid (the electron density) rather than in the fields. Then you end up with this drift velocity nonsense which is essentially a holdover from the Drude model which is only predictive by luck.
