The line on the earth's surface joining the points where the earth's magnetic field is horizontal is called (A) Magnetic meridian (B) Magnetic axis (C) Magnetic line (D) Magnetic equator
Magnetic field of earth is identical to magnetic field of a giant magnet held $20^{\circ}$ west of geographic $N-\mathrm{S}$ at the centre of earth. At equator, horizontal component of earth is 0.32 G. Vertical component can be calculated from the relation $V=H \tan \delta$, where $\delta$ is angle of dip at the place. The value of $\delta=0^{\circ}$ at equator and $8=90^{\circ}$ at poles. At a particle place, $V=H$. The angle of dip is (a) 45 * (b) $90^{\circ}$ (c) $0^{\circ}$ (d) None of these
