Michel, lol, you are tying yourself up in a knot something terrible. A current loop is not closed. It seems you understood this, "It should indeed be attracted and accelerated towards the short-circuited current loop so KE will be gained" If the electro-magnet is magnetically attracted to the current loop then the current loop is an open magnetic field, surprise. This is too funny, a current loop by itself is not closed. If you are talking about a toroid, where the magnetic field is closed then there will be no magnetic attraction. This is getting silly. Perhaps someone is simply trying to waste my research time. Heavens forbid, we wouldn't want someone giving the world "free energy." That could temporarily cause world chaos economically and result in a beautiful and stabilized system.
