If the Allies take Copenhagen do the minefields preventing UK ships to sail in to the Baltic disappear? If yes, do they return if the Germans take back Copenhagen?

yes and yes

More generally, the way I believe minefields work is:
1) They are never removed, except perhaps by some events (?)
2) They are "owned" by whoever owns the land hex that they share, even if it's just a beach side.
3) They will block sea movement by whatever side doesn't own them.

So while you can only move into beach hexes through invasion, if you move next to them and they're unoccupied, you will capture them immediately and gain control of the minefield.

So, for example, the allies could invade next to the minefield in southern Norway and the occupy it, allowing them to immediately move to invade Oslo. Likewise if they take both that minefield and the adjacent one in northern Denmark, the Axis could no longer move through those zones (note that they can still use the Kiel Canal, so it doesn't prevent movement into the Baltic).

I realize this might be confusing since this is absolutely not how minefields work in reality, but it makes for some very cool tactical choices in the game, which I really like.
