Is a divorce considered to have taken place in the aforementioned situations, given the presence of symptoms of a magic spell causing separation and extreme anger, and what is the number of divorces that have occurred?

The wife is under the marital authority of her husband after he divorced her twice and took her back through intercourse after the second divorce. Intercourse is considered a return (to the marriage) even if there was no intention (of doing so). What they find of papers, threads, and symptoms may be magic (sihr), and they must go to someone who can recite over them to invalidate the magic and treat it, while maintaining the regular recitation of dhikr (remembrance of Allah), Surah Al-Baqarah, Ayat Al-Kursi, and Al-Mu'awwidhatayn.
