At a certain place the horizontal component of earth’s magnetic field is a √3 time the vertical component, the angle of dip is
15o
30o
45o
60o
The vertical component of the earth’s magnetic field is zero at a place where the angle of dip is
0o
90o
If the earth’s horizontal and vertical components are equal at a certain point, the angle of dip is,
Zero
The earth’s magnetic field always has a vertical component except at,
Magnetic equator
Magnetic poles
Geographic pole
Attitude 45o
The angle between the magnetic meridian and geo meridian is known as
Magnetic dip
Magnetic declination
Magnetic latitude
Magnetic longitude
The correct value of dip angle at a place is 45o. If the dip angle is rotated 45oout of the meridian, the tangent of the apparent dip is
1
1/√2
√2
1/2
If a magnet is suspended at an angle of 30° to the magnetic meridian, the dip needle makes an angle of 45° with the horizontal. The real dip is:
tan-1 (√ 3 / 2)
tan-1 (√ 3 )
tan-1 ( 2/√3 )
tan-1 (2 )
What is the value of dip at the magnetic pole?
zero
At a certain place the magnetic fields horizontal component is BH and the angle of dip is 45o. The earth’s total field at that place is

At a certain place, horizontal component is √3 times the vertical component. The angle of dip of this place is
