Question

The horizontal and vertical components of the Earth's magnetic field at a place are each equal to $0.35$ gauss. Find the angle of dip at the places.

Answer 1

Relation between vertical and horizontal component of earth's magnetic field is given by
$B_V=B_H\tan \delta$
where $\delta$ is the angle of dip at that place.
Given : $B_H=B_V=0.35$ Gauss
$⟹\tan \delta =1$
$⟹\delta ={45}^o$
