Grad Undergrad Faculty Other I have done this pretest tutorial before PRETEST MAGNETS AND MAGNETIC FIELDS 1 At the four labeled points A D sketch a vector representing the magnetic field around the bar magnet A B N S D C 2 A second bar magnet identical to the first one is now placed to the left of point A At the four labeled points A D sketch a vector representing the magnetic field of both magnets A N S B N S D C 3 Rank the magnitude of the magnetic field at the points A B A and B If the magnitude of the magnetic field at any point is zero state that explicitly Explain your reasoning If you cannot determine the ranking explain why not continued on other side Tutorials in Introductory Physics EM UCO1110044T P9 MMF V1d McDermott Shaffer P E G U Wash Autumn 2004 4 An uncharged piece of cork is hung from a string When a positively charged rod is brought near but not touching the cork the rod attracts the cork and the cork hangs as shown Charged rod Piece of Cork A On the diagram sketch how the piece of cork would hang if the north end of a magnet were brought near the cork Explain your reasoning North end of magnet B On the diagram sketch how the piece of cork would hang if the south end of a magnet were brought near the cork Explain your reasoning South end of magnet Tutorials in Introductory Physics EM UCO1110044T P9 MMF V1d McDermott Shaffer P E G U Wash Autumn 2004
