QUIZ 7~   CH. 27
EXERCISES/PROBLEMS
Magnetic fields --a basic description  of field lines--they form loops with no beginning or end with an emphasis on  magnetic forces:  Magnetic forces only act on moving charges. THE STARTING POINT OF THE ENTIRE DISCUSSION FOR CHAPTERS 27 AND 28  IS THE BEGINNING OF SECTION 27.2: Magnetic fields are caused by moving atomic  charges (i.e.,  electrons)  and only moving charges experience the magnetic force.  IN THIS CHAPTER WE EMPHASIZE  MOVING CHARGES OR CURRENTS AS SOURCES  THE MAGNETIC FIELDS.
