Answer 1

It's a common mode choke (Common Mode Coil), like this:

Or maybe it's for sure. Just in case, here is a pdf description , compare the geometric dimensions, call.
The good news is that the part is most likely intact. There is nothing to break there - stupid wire. You can check with a meter. The connection diagram should be like this:

длинная сторона
[_]---------[_]

[_]---------[_]

Bad news: torn off along with pieces of tracks. If the board has foil residue on all four patches, you can try soldering. If the patch is completely torn off, look for the path leading to it, clean it up and build it up with wire.

Answer 2

It looks like a winding product, such as a coil. Have a higher resolution photo?
