question 30

the north magnetic pole of a compass needle is attracted to the _____ magnetic pole of the earth.
a. south
b. west
c. east
d. north

Explanation:

Apply the law of magnetic poles

Using the Magnetic Poles Law knowledge point

$$ \text{Opposite magnetic poles attract, while like magnetic poles repel.} $$

Determine the attraction of the compass needle

Using the Earths Magnetic Field knowledge point

$$ \text{The north-seeking pole (north pole) of a magnet is attracted to a magnetic south pole.} $$

Since the north magnetic pole of a compass needle points toward the geographic North Pole of the Earth, the Earth's magnetic pole located near the geographic North Pole must be a magnetic south pole. Therefore, the north magnetic pole of the compass needle is attracted to the south magnetic pole of the Earth.

Answer:

• a. south (Correct answer)
• b. west
• c. east
• d. north
