If that pen is geometric axis of earth,the book is its meridian. Magnetic Declination is defined as the angle made by the Magnetic meridian with the geographic meridian. (e) Magnetic Meridian (MM) : (i) It is a vertical plane at any place which passing through magnetic axis of the earth. 4.2 DEFINITIONS. For a vertical plane other than magnetic meridian $\alpha>0$ or $\cos \alpha<1$ so $\theta^{\prime}>\theta$ In a vertical plane other than magnetic meridian angle of dip is more than in magnetic meridian. However, a compass needle will not be steady in the magnetic meridian, because of the longitude from east to … 1 answer. The magnetic pole is not fixed in position but rather changes its position continually. The angle that magnetic meridian makes with the horizontal is … The period of oscillation of a dip needle when vibrating in the magnetic meridian is 1.5s.
