प्रश्न
What is the angle of dip at a place where the horizontal and vertical components of the Earth’s magnetic field are equal?

उत्तर
The angle of dip is given as
`S = tan^-1 ((B_v)/(B_H))`
BV = vertical component of earth’s magnetic field.
BH = horizontal component of earth’s magnetic field.
So, as BV = BH, then
S = tan−1 (1)
Or the angle of dip will be, S = 45°
