Question

horizontal component of earth's magnetic field at poles and equator
​

Answer 1

Answer:

At the poles, the direction of the field is perpendicular to the earth's surface, whereas at the equator, the field is parallel with the earth's surface. Since the horizontal field is very weak north and south of 75° magnetic latitude, it is impossible to rely on a compass in the polar regions.
