Question 10 / 0.5 ptsFrom which end (North or South) of a bar magnet do magnetic field lines emerge?You Answered South Correct Answer
North Question 20.5 / 0.5 ptsDo the field lines really start at the pole face? Yes Correct! No Question 31 / 1 ptsDo magnetic field lines ever start or end anywhere? Yes Correct! No Question 41 / 1 ptsA freely pivoting bar magnet (such as a compass needle) is placed in a magnetic field created by other sources. True or False: The figure correctly shows the alignment of the compass in the external magnetic field.
True Correct! False Question 50 / 1 ptsThe earth’s magnetic field appears as if it were produced by a strong permanent magnet embedded in its core. In the figures below, the earth is shown with the northern hemisphere on top, its core magnet is illustrated by the overlaid bar magnet, and a compass is illustrated as a diamond with a black tip at its magnetic north end. Which figure has the core magnet and compass magnet in roughly the proper orientation?
Figure 1 You Answered Figure 4 Figure 2 Correct Answer Figure 3
