Abstract
Magnetic reconnection is the key to explosive phenomena in the universe. The flux rope is crucial in three‐dimensional magnetic reconnection theory and is commonly considered to be generated by secondary tearing mode instability. Here we show that the parallel electron flow moving toward the reconnection diffusion region can spontaneously form flux ropes. The electron flows form parallel current tubes in the separatrix region where the observational parameters suggest the tearing and Kelvin‐Helmholtz instabilities are suppressed. The spontaneously formed flux ropes could indicate the importance of electron dynamics in a three‐dimensional reconnection region.
