the horizontal and vertical component of magnetic field on earth are same at the place on the surface of earth the magnetic dip angle at this place will be
Answers
TheThe dip angle ‘A’ at a point is defined as the angle between the direction of the Earth’s magnetic field ‘B’ and the horizontal at that point on the surface of the Earth.
\tan^{-1}A=\dfrac{B_v}{B_h}tan

= vertical component of earth’s magnetic field
B_h=B

= horizontal component of earth’s magnetic field
Given: B_v=B_hB

Substituting (2) in (1)
Hence \tan^{-1}A=\dfrac{B_h}{B_h}tan

Hence the correct option is (B). dip angle ‘A’ at a point is defined as the angle between the direction of the Earth’s magnetic field ‘B’ and the horizontal at that point on the surface of the Earth.
