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.

At a certain location in Africa, a compass needle points 15^@ west of the geogrphic north. What is the angle of declination at the point ?

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.

A magnetic needle free to rotate about the vertical direction (compass ) point 3.5 west of the geographic north . Another magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 18^(@) with the horizontal . The magnitude of the horizontal component of the earth ' magnetic field at the place is known to be 0.40 G . what is the direction and magnitude of the earth's magnetic field at the place ?

The line joining the points of horizontal component of earth's magnetic field is called

What is the angle of dip at a place where the horizontal and vertical component of earth magnetic field are equal?

The horizontal component of the earth's magnetic field at a place is B_H and angle of dip is 60^@ What is the value of vertical component of earth's magnetic field at equator?

The horizontal and vertical components of earth's magnetic field at a place are 0.22 G and 0.38G respectively. Calculate the angle of dip.

The ratio of the horizontal component to the resultant magnetic field of earth at a given place is 1//sqrt2 . What is the angle of dip at that place?
