Hall coefficients and resistivities of high-Tc YBa2Cu3Oy (YBCO) films in the mixed state have been measured in the temperature ranges below Tc to explore the correlation between the negative Hall coefficient and the flux flow resistivities. The negative Hall coefficient in the mixed state of YBCO films shows a local minimum; which corresponds to the flux flow regime in the resistivity data. The negative Hall coefficients is explained in terms of the charge accumulation due to the induced electric fields Exy,ind, where Exy,ind is the component of induced electric field Eind along a direction perpendicular to the transport current js.
