The compass error of a magnetic compass that has no deviation is _______________.
AI Explanation
The correct answer is B) equal to variation.
The compass error of a magnetic compass that has no deviation is equal to the variation, which is the angle between true north and magnetic north at a given geographical location. Variation changes depending on the location, but for a compass with no deviation, the only remaining compass error is the variation.
The other options are incorrect:
A) is incorrect because the variation changes depending on the geographical location.
C) is incorrect because adjusting the compass only eliminates the deviation, not the variation.
D) is incorrect because the compass error is not zero if there is variation present.
