Write the value of
vertical component of Earth's magnetic field.

Text Solution

Verified by Experts

Vertical component :
The Earth's magnetic field is perpendicular to the surface of the Earth (i.e., vertical ) which implies that the needle of magnetic compass rests vertically at an angle of dip, `I = 90^(@)` as shown in Figure
Hence,
` H_(H) = 0 `
` B_(V) = B_(E)`
This implies that the vertical component is maximum at poles and horizontal component is zero at poles.
