Question

The horizontal component of the earth’s magnetic field at a place is B and angle of dip is 60°. What is the value of vertical component of earth’s magnetic field at equator?

Answer 1

On the equator, the values of both angle of dip (δ) and vertical component of earth’s magnetic field is zero. So, in this case, Bv = 0.

Answer 2

Answer:

Explanation:

Given the statement that vertical component of the magnetic Bv is under root 3 times the horizontal component of magnetic field Bh, which implies that the ratio of the vertical component of magnetic field to the horizontal component of magnetic field equals to  under root 3;

Bv/ Bh = √3

But the basic formula says that; Bv/ Bh = Tanδ

So comparing both the equations, we'll achieve;

Tanδ = √3 , and Tangent function gives the value of √3 at the angle of 60° so the angle of dip is 60°

δ = 60°
