Abstract:
We have investigated the amount of heating due to an external source for some coronal loops and kernels in the line-dipole and the point dipole geometrics under nonstatic conditions. Two forms for the external source are considered. It is found that the amount of heating for the line dipole geometry is larger than that for the point-dipole geometry. Further, the amount of heating is larger when the source is extended one (large value of gama). The heating for the second form of the source is found larger than that for the first form in the line-dipole geometry, whereas in the point-dipole geometry the reverse is true.
