Originally a compass placed at location A points North. Then a bar magnet is placed at the location shown in the diagram, with its center 16 cm from location A . With the magnet present, the compass needle points 75 degrees East of North. Which pole of the magnet is nearer to location A ?North North Which arrow best represents the direction of the magnetic field at location B , due to the bar magnet?g g Which arrow best represents the direction of the magnetic field at location C , due to the bar magnet?c c Which arrow best represents the direction of the magnetic field at location D , due to the bar magnet?g g What is the magnetic dipole moment of the bar magnet? = 1.528648 1.53 A*m 2 Solution or Explanation The bar magnet is a magnetic dipole, so the pattern of magnetic field around it is the familiar dipole field pattern.
