EXERCISES/PROBLEMS. NOTE: THE "MP" TAG, when it appears, means the problem comes highly recommended but is not to be turned in; you could be tested on it in any event; don't sleep ! READ ALL EXAMPLES IN THE CHAPTER. |
HYPERPHYSICS NOTE: THIS HYPER PHYSICS LINK , MAGNETISM, |
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 OF THE MAGNETIC FIELDS. |
