  Observational evidence of the braiding of magnetic field lines has been
reported. The magnetic reconnection within the loop (nanoflares) and with other
loops (microflares) disentangle the field. The coronal field then reorganizes
itself to attain a force-free field configuration. We have evaluated the power
law index of the energy distribution $f(E)=f_0 E^{-\alpha}$ by using a model of
relaxation incorporating different profile functions of winding number
distribution $f(w)$ based on braided topologies. We study the radio signatures
that occur in the solar corona using the radio data obtained from the
Gauribidanur Radio Observatory (IIA) and extract the power law index by using
the Statistic-sensitive nonlinear iterative peak clipping (SNIP) algorithm. We
see that the power law index obtained from the model is in good agreement with
the calculated value from the radio data observation.
