PPT-THE ROLE OF MAGNETIC FIELDS

Christopher F McKee MFU V Corsica Oct 7 2015 With Pak Shing Li Richard Klein IN STAR FORMATION Partial support provided by the National Science Foundation and NASA OUTLINE III Observing interstellar magnetic fields on a computer LMK. 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 Sunspot magnetic fields fields What are Sunspots?
