Question

Earths total magnetic field at equator to that at north pole is

Answer 1

Answer:

The field at the poles is ≈ 60 000nT, whereas it is ≈ 30 000nT at the equator. At the poles, the direction of the field is perpendicular to the earth's surface (figure 2.8), whereas at the equator, the field is parallel with the earth's surface. The direction of the field in space changes with magnetic latitude.
