PPT-“Insights” on Coronal Hole Magnetic Fields From a High-

DJ Bercik and JG Luhmann Space Sciences Lab UC Berkeley 1 FEW 2011 Aug 24 Introduction The two most viable models of solar wind energization both ultimately appeal to convective granular flows. In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir in Solar Disk Images .
