Q. Let $B_{V}\ and\ B_{H}$ be the vertical and horizontal components of earth’s magnetic field at any point on earth. Near the north pole
A) $B_{V} > > \ B_{H}$
B) $B_{V} < \ < B_{H}$
C) $B_{V} = B_{H}$
D) $B_{V} = B_{H} = 0$
Explanation
(a) Near the north and south poles, the field points directly into or out of the earth. Near the equator the field is parallel to the surface. Near cleveland the earth’s magnetic field has a north-south horizontal component and a much larger vertical component into the ground.

F = total intensity magnetic field vector
H = horizontal component of magnetic field vector
V = the vertical component of magnetic field vector.
