✦ Synopsis

Recent observations of the motion of the fl)otpoinls of tl~e bipolar magnetic iiekts of aclive X-ray regions of the Sun establish that the footpoints are intermixed on file same characteristic time and scale as the granule motions. It follows that the bipolar magnetic fields have an internally interlaced topology creating magnetic free energy. It follows from the basic theorem of magnetostatics that the Iopology creates internal surfaces of tangential discontinuily which e 'ective y dissipate I fie magnetic fiee energy into heat. This process appears to be the cause of the X-"z y coronae of solitary late Main-Sequetme stars like the Sun.
