Question

At a certain place on earth, the horizontal component of earth's magnetic field is 3 times of its vertical component. The angle of dip at that place is

Answer 1

Horizontal and vertical components of Earth's magnetic field are equal at magnetic North and South poles. At these positions angle of dip will be 90° because direction of magnetic field of Earth is along the magnetic axis.Feb 25, 2018

Answer 2

Answer:

The angle of dip at that place is 60°.

Explanation:

Given that,

The ratio of vertical component and horizontal component of magnetic field  is

$\dfrac{B_{v}}{B_{H}}=\sqrt{3}$

Where, $B_{v}$ is the vertical component of earth's magnetic field

$B_{H}$ is the Horizontal component of earth's magnetic field

We need to calculate the angle of dip at that place

Using formula of angle

$\tan\theta=\dfrac{B_{v}}{B_{H}}$

Put the value of vertical and horizontal component of magnetic field

$\tan\theta=\sqrt{3}$

$\theta=\tan^{-1}(\sqrt{3})$

$\theta= 60^{\circ}$

Hence, The angle of dip at that place is 60°.
