I'm surprised nobody has got back to you on this one since this is the most likely place to come to for answers relating to magnetism, electromagnetism and electromagnetic induction
Think of magnetic energy as an onion
Each layer is supported by the lower layers and from 1st principles they form complete bands; take the shortest possible route, ie. in contraction, but at the same time the energy flowing in the same direction is in repulsion.
So we have bands of energy each repelling one another but also compact due to conserving its length of magnetic path.
A sort of energy field which when acted upon by outside influences such as a conductor will release or convert its energy in the form of an emf in the conductor.
