Consider the plane S formed by the dipole axis and the axis of earth. Let P be 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 angles at P and Q.

Text Solution

Verified by Experts

Let point P is in the plane S, needle is in north, so the declination is zero.

Since point P lies in plane S formed by the dipole axis and the axis of the Earth, declination is zero. Since point Q lies on the magnetic equator angle of dip is zero.
It is 11.3° tilted with its axis of the earth so declination between P and Q is 11.3°.
