Answer» Correct answer is (a) When the VERTICAL and HORIZONTAL components of earth’s magnetic FIELD are equal The best I can explain: YES, the angle of dip at a place is equal to 45^o, when the vertical and horizontal components of earth’s magnetic field are equal. In this case ➔ δ=45^o tanδ=\( \FRAC {B_V}{B_H}\)=1 So, BV=BH.
