Let the magnetic field on earth be modellel by that of a point magnetic dipole at the centre of earth. The angle of dip at a point on the geographical equator.

The magnetic field of Earth can be modelled by that of a point dipole placed at the centre of the Earth. The dipole axis makes an angle of 11.3° with the axis of Earth. At Mumbai, declination is nearly zero. Then,
