Question

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 horizontally on the equator, with the north end facing north america. b. place the magnet vertically on the equator, with the south end facing the north pole. c. place the magnet horizontally on the equator, with the south end facing north america. d. place the magnet vertically on the equator, with the south end facing the the south pole.

Explanation:

Earth's magnetic field is approximately horizontal at the equator. A bar magnet should be placed horizontally. Also, the north - seeking pole of a magnet is attracted to Earth's magnetic south pole (near Earth's geographic north pole). So the north end of the bar magnet should face north.

Answer:

A. Place the magnet horizontally on the equator, with the north end facing North America.
