At the time that core started separating apart, that inductor / transformer then transitioned from being an effective inductance to a being a low resistance, the degree, being in accordance to the distance of separation.
OBSERVATION. . . .
Hmmmmmmmmmm . . . . . that center of the core E must be quite a loose / sloppy fit in order to let that wide slant develop . . . .that the loose E-core is presently now seen..
NOW we don't know FOR SURE if we have winding damage*** incurred so why not go for broke and try a refix of the separated core halves !
Now if you don't know " NUTTINS " 'bout ferrite transformer cores, you don't just slap their two halves FLUSH together, since their design aspect is wanting to avoid a possibility of full saturation of the core. So expect two specifically sized, small insulative spacers, being centered within and keeping the two core halves apart on your re assemblage of the unit .
I think I might see one, centered within the most visible portion at the outermost extended E-core .
You know of black plastic tape, but I see then using BLUE tape for their circumferal, core wrap arounds, but their plastic tape is being of the type that snaps or tears . . . . . but NOT stretches . . .like our family of black electrical tape would . . . . and you do NOT want a stretch effect , if being used for binding.
*** Put yer nose RIGHT up against the central winding and its edges to see if you can smell any burnt effect ?
If being my repair , I would already be having on hand, heat resistant KAPTON tape for the initial core wraparound and an outer binding choic of either radio dial cord, nylon fishing line ( NOT monofilament ! ) or two families of waxed cable lacing . . .flat or cord.
However, a John Public might only have 3M clear package wrapping tape and some type of twine / cord or heavy thread to bind with.
Then, I would not even bother in using a FOREVER commitmemnt . . . of super glue or epoxy family as an adhesive. Using no adhesive at all.
Instead I just measure off a 2 full wrap length of tape, cut to core width, if being overly wide, and then some HARD finger clamping of the core halves together while winding on the CONTINUALLY HARD tensioned tape until the 2 full turn stage.
Then over wrap the tape winding with an equally hard tensioned application of side by side turns of cord until having a full width wrap.
Then a tight knotting and a hold off of a cement blob to that knot heads application until making a final power up evaluation and some serious shake down / run time.
Thaaaaaaasssit . . . . . .
