The earth's magnetic field

A place where the vertical components of Earth's magnetic field is zero has the angle of dip equal to

At a certain location in Africa, the north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points ${60}^{\mathrm{o}}$ above the horizontal. The horizontal component of the earth's field is measured to be $0.16 \mathrm{G}$. At that position a compass points ${12}^{\mathrm{o}}$ west of the geographic north. Specify the magnitude of the earth's field at that location.

Let the magnetic field on earth be modelled by that of a point magnetic dipole at the centre of earth. The angle of dip at a point on the geographical equator is
