Question:
Consider the plane S formed by the dipole axis and the axis of the earth. Let P be a point on the magnetic equator and in S. Let Q be the point of intersection of the geographical and magnetic equators. Obtain the declination and dip angle at P and Q.
Solution:
Point P is in the plane, S is in the north and the declination is zero.
The declination is zero for point P as the point lies in the plane S formed by the dipole axis and the axis of the earth
The angle of dip is zero for point Q as the point Q lies on the magnetic equator and the angle of declination is 11.3o.
