Annotation	MHD simulation spanning over five scale magnitudes demonstrated multiple levels of the energy cascade in magnetic reconnection: Subsequent tearings in small scale current sheets formed between separating plasmoids. It revealed also further type of fragmentation - it was shown that current layer formed between two merging plasmoids is subjected to plasmoid instability when its aspect ratio reaches the threshold. Hence, also plasmoid coalescence contributes to energy cascade towards small scales.
