Chapter 4, Problem 1RQ
To determine
Whether the north magnetic pole of the earth is a north polarity or a south polarity?
Expert Solution & Answer
Answer to Problem 1RQ
The north magnetic pole of the earth is a south polarity.
Explanation of Solution
Description:
The earth itself contains magnetic poles. As unlike poles attract each other, the north magnetic pole of a compass needle is attracted to the south magnetic pole of the earth and vice versa.
Hence the north magnetic pole is a geographic south pole.
Conclusion:
The north magnetic pole is a geographic south pole.
