Thank you. I got a hint from your explanation, so I could search the information in own my language.

Good question, but I think you should find a better title, one that actually describes the question.

In this case, I think the term "short circuit" is inaccurate and I understand your confusion.  I've also seen it described as the magnetic field lines "snapping" leading to the coronal mass ejection.  But neither "snap" nor "short circuit" does a good job of explaining what actually happens (and I'm not sure I should try as I don't have a good grasp of the specifics).  but see here for some explanation:   http://www.space.com/22393-sun-magnetic-field-explained-infographic.html and here a person tries to explain the process.

Forgot to include the link, but I like this description, because a magnetic field "line" isn't a physical thing, it's a model that explains the magnetic force, there's nothing to "snap", so short circuit is maybe a better term, but still inadequate.    All this said, some of your questions could probably be answered by a bit of google and research, not just posting a page and saying "I don't understand".   Try to formulate specific questions beyond "what does this mean?".   https://www.physicsforums.com/threads/how-can-magnetic-field-lines-snap.394949/

@userLTK Thanks for your kind. It was very useful to me because I got a hint your comment. I solved my problem due to you.
