Vedclass · Answer

(C) The angle of dip (or magnetic inclination) $\delta$ is defined by the relation $	an \delta = \frac{V}{H}$,where $V$ is the vertical component of the Earth's magnetic field and $H$ is the horizontal component.At the magnetic equator,the Earth's magnetic field lines are parallel to the surface of the Earth.Therefore,the vertical component $V$ of the Earth's magnetic field is zero at the magnetic equator.Substituting $V = 0$ into the formula,we get $	an \delta = \frac{0}{H} = 0$,which implies $\delta = 0^\circ$.Thus,the correct option is $C$.

The value of the angle of dip is zero at the magnetic equator because on it:
