Question

Horizontal component of earth's magnetic field at a place is √3 times the
vertical component. What is the value of inclination at that place?​

Answer 1

Given:

Horizontal component of earth's magnetic field = √3 times the vertical component

To find:

Value of inclination at that place.

Solution:

At any place on the earth the magnetic field of earth has two components, one is the horizontal one and the other is the vertical one.

Let Bh= Horizontal component

Bv = Vertical component

α = Angle of dip

As given: Bh = 1/√3 Bv     eq(1)

Therefore, Bv = √3 Bh

We know that tan α = perpendicular/ base

tan α = √3 Bh/Bh

tan α = √3

so, α = 60°

Therefore, the required angle of dip is 60°.
