The angle of dip at a certain place can be calculated using the following formula:

tan δ = Bv/Bh

where δ is the angle of dip, Bv is the vertical component of the Earth's magnetic field, and Bh is the horizontal component of the Earth's magnetic field.

Given that Bh = 3Bv, we can substitute this into the formula:

tan δ = Bv/(3Bv) = 1/3

Taking the inverse tangent of both sides, we get:

δ = tan⁻¹(1/3)

Using a calculator, we find that:

δ ≈ 18.43°

Therefore, the angle of dip at that place is approximately 18.43°.

Horizontal component should be √3 times the vertical component.
using the relation
Bv/Bh = tan∆
tan∆ = 1/√3
∆ = 30
