's magnetic field is zero?

The angle of dip or inclination is the angle between the direction of the Earth's magnetic field lines and the horizontal plane. When the horizontal component of the Earth's magnetic field is zero, the magnetic field lines are perpendicular to the horizontal plane, and the angle of dip is 90 degrees. This occurs at the magnetic poles, where the magnetic field lines converge and are vertical.

Let angle of dip = ∆ We know that , tan ∆ = V/H ...(i) where , V and H are the vertical and horizontal components . According to the question , V =H ...(ii) Now , From (i) , tan ∆ = V/H or , tan ∆= V/V from (ii) or , tan ∆ = 1 or , ∆ = 45 degrees Therefore required angle of dip is 45 degree. Answer : c
