Which limitation arose when using early Islamic astrolabes for navigation near Earth's magnetic poles?

💡 Explanation

Near magnetic poles, magnetic declination affects compass readings, so alignments based on magnetic north induce errors in the celestial alignment of the astrolabe. Therefore declination errors influencing alignment result, not timekeeping issues, material expansion or atmospheric refraction, which stem from other environmental factors and design flaws.
