The Hall effect is suggested to be responsible for decoupling of electrons and ions in plasma during magnetic reconnection. It leads to redistribution of charged particles during magnetic reconnection. In this paper, charge distribution brought about by the Hall effect during magnetic reconnection is studied by using compressible Hall magnetohydrodynamics numerical simulation. Decoupling of electrons and ions in plasma can be clearly shown in this numerical simulation result. The bimodal structure of electron distribution in the electron diffusion region as well as its motion during magnetic reconnection have been found and discussed.
