The energetics of driven magnetic reconnections induced by the deformation
of the magnetopause boundary due to the solar wind-magnetosphere interactio
n are studied. The bursty type reconnection ensues due to the forcing of th
e magnetopause boundary by the solar wind. For typical plasma parameters in
the inner central plasma sheet (ICPS), the magnetic energy release during
the reconnection is estimated and it is found that the available free energ
y is comparable to the observed kinetic energy of typical bursty bulk flows
. It implies that the part of the free energy goes into the heating of the
ICPS particles, whereas the rest goes into its acceleration. The accelarate
d particle manifests itself as bursty flows.
