We study the correlation between the speed of two-ribbon separation and the magnetic flux density during the 2001 April 10 solar flare. A weak negative correlation is found between the ribbon separation speed (Vr) and the longitudinal magnetic flux density (Bz). In addition, we estimate the magnetic reconnection rate (Erec). Along the flare ribbons, Erec fluctuates in the small range except near the HXR source. The localized enhancement of the reconnection rate corresponds to the position of the HXR source.
