Angle Of — Dip
BV=Bsin(θ)cap B sub cap V equals cap B sine open paren theta close paren To find the angle of dip directly from the components:
BH=Bcos(θ)cap B sub cap H equals cap B cosine open paren theta close paren angle of dip
A specialized needle used to measure inclination. BV=Bsin(θ)cap B sub cap V equals cap B
