Answer:

HOPE IT WILL HELP YOU

Explanation:

Magnetic Inclination: It is the angle made by resultant magnetic field of earth with the horizontal. It is also called angle of dip.

Relation, suppose

Be

is earth's net magnetic field, θ is angle of dip. Resolving

Be

along horizontal and vertical direction; the horizontal component is H and vertical component is V From fig cosθ=

B

e

H

∴H=B

e

cosθ

This is the required relation.
