question 4 of 10
which statement correctly describes how a bar magnet should be placed on a globe to correctly align with earths magnetic field?
a. place the magnet vertically on the equator, with the north end facing the north pole.
b. place the magnet vertically on the equator, with the south end facing the the north pole.
c. place the magnet horizontally on the equator, with the north end facing south america.
d. place the magnet horizontally on the equator, with the south end facing south america.

Explanation:

Earth's magnetic field is similar to that of a bar magnet. The Earth's magnetic north pole is near the geographic south pole, and the magnetic south pole is near the geographic north pole. Opposite poles attract. At the equator, the magnetic field is horizontal. South America is in the southern hemisphere. So the south end of the bar magnet should face South America (which is near the Earth's magnetic north - like pole).

Answer:

D. Place the magnet horizontally on the equator, with the south end facing South America.
