	The angle between the earth's magnetic and the earth's geographical axes is
	The lines joining the places of the same horizontal intensity are known as
	Ratio between total intensity of magnetic field at equator to poles is
	A line passing through places having zero value of magnetic dip is called
	At a place, the horizontal and vertical intensities of earth's magnetic field is 0.30 Gauss and 0.173 Gauss respectively. The angle of dip at this place is
	The angle of dip at a place is 60°. At this place the total intensity of earth's magnetic field is 0.64 units. The horizontal intensity of earth's magnetic field at this place is
	The magnetic compass is not useful for navigation near the magnetic poles because
	The angle of dip at a place on the earth gives
	At the magnetic north pole of the earth, the value of horizontal component of earth's magnetic field and angle of dip are, respectively
	At a place, the magnitudes of the horizontal component and total intensity of the magnetic field of the earth are 0.3 and 0.6 Oersted respectively. The value of the angle of dip at this place will be
