Lab: Magnetic and Electric Fields — Unit test

Question 1 • FL-2003310-Physical Science CR

Which statement correctly describes Earth’s magnetic field?

Answer
A
A compass can lead a hiker to the geographic North Pole.
B
The magnetic pole near the South Pole is a north pole.
C
Compasses point toward a magnetic pole that is a north pole.
D
Field lines circle Earth from east to west.

Explanation

A compass’s north-seeking end is attracted to a magnetic south pole. Since it points roughly toward the geographic North Pole, the magnetic pole near the South Pole must be a north pole. Thus, “The magnetic pole near the South Pole is a north pole” is correct; a compass does not point directly to the geographic North Pole.
