And when the power source is disconnected, this energy comes back into the circuit and tries to maintain the current at its previous level. It fails, of course, but in the process it raises the voltage across the inductor abruptly, sometimes to disastrously high levels, during the few moments the energy is available.

electric fields

The key learning here is that we store mechanical energy in a GRAVITATIONAL field. WE store electrical energy in an ELECTRIC field. The real question is not "why did the voltage go up" but rather, "why does a gravitation field or electrical field allow us to store energy within it." And that is where the real mystery continues to lie.
