At a point A on the earth's surface the angle of dip, . At a point B on the earth's surface the angle of dip, . We can interpret that:
A and B are both located in the northern hemisphere.
A is located in the southern hemisphere and B is located in the northern hemisphere.
A is located in the northern hemisphere and B is located in the southern hemisphere.
A and B are both located in the southern hemisphere.
Angle of dip is the angle between earth's resultant magnetic field from horizontal. Dip is zero at equator and positive in northern hemisphere. In southern hemisphere dip angle is considered as negative.
