However, the process of CR acceleration and the trigger mechanism of magnetar transients remains unclear. A recently suggested scenario for the activity predicts that the magnetar's rotation axis suddenly flips due to the `Dzhanibekov effect,' resulting in a sudden rise of the Euler force. The material in the outer layer plastically flows due to the force and finally fractures in this scenario.
