Question

What is the value of magnetic dip at a place where BH= 0?

Answer 1

The angle made by the earth's total magnetic field with the horizontal direction is called angle of dip at the given place.

$tan$ $\delta$$=B_V/B_H$

where $\delta$ is the angle of dip

so when $B_H=0$ then the value of $tan\delta$ will be approaching infinity

Hence value of $\delta$ will be equal to 90⁰
