A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at `22^@` with the horizontal. The horizontal component of the earth’s magnetic field at the place is known to be 0.35 G. Determine the magnitude of the earth’s magnetic field at the place.

A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 60^@ with the horizontal. The horizontal component of the earth's magnetic field at the place is known to be 0.4 G. Determine the magnitude of the earth's magnetic field at the place.

At a certain location in Africa, a compass points 12^@ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points 60^@ above the horizontal. The horizontal component of the earth’s field is measured to be 0.16 G. Specify the direction and magnitude of the earth’s field at the location.
