FIGURE 29-3
-Fig. 29-3 above shows a bar magnet moving upward along the vertical axis toward a horizontal coil. The poles of the bar magnets are labeled X and Y. As the bar magnet approaches the coil it induces an electric current in the direction indicated on the figure. What are the correct polarities of the magnet?

A) X = south , Y = north
B) X = negative, Y = positive
C) X = positive, Y = negative
D) X = north, Y = south
E) The polarities of the magnet cannot be determined from the information given.
