We investigate the dynamical fragmentation of magnetic flux tubes during two tubes collision, by changing the radius as well as the current intensity of the flux tubes. Our simulation results show that there occurs fragmentation of a magnetic flux tube with weak current and small radius, when it collides with a flux tube with strong current and large radius. The heating process during the collision of two flux tubes would be important for understanding complicated dynamics of magnetic bright points (MBPs) in the quiet photospheric network.
