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.

The declination is zero, P is in the plane, S is in the north, and P is in the plane.

The declination for point P is 0 since it is in the plane S created by the dipole axis and the earth’s axis.

Because point Q is on the magnetic equator and the angle of declination is 11.3o, the angle of dip is zero.
