Consider the plane $\mathrm{S}$ formed by the dipole axis and the axis of earth. Let $\mathrm{P}$ be point on the magnetic equator and in $\mathrm{S}$. Let $\mathrm{Q}$ be the point of intersection of the geographical and magnetic equators. Obtain the declination and dip angles at $\mathrm{P}$ and $\mathrm{Q}$
Let point $\mathrm{P}$ is in the plane $\mathrm{S}$, 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 $11.3^{\circ}$ tilted with its axis of the earth so declination between $P$ and $Q$ is $11.3^{\circ}$.

A fighter plane of length $20\, m$, wing span (distance from tip of one wing to the tip of the other wing) of $15\,m$ and height $5\,m$ is lying towards east over Delhi. Its speed is $240\, ms^{-1}$ . The earth's magnetic field over Delhi is $5 \times 10^{-5}\,T$ with the declination angle $ \sim {0^o}$ and dip of $\theta$ such that $\sin \,\theta = \frac{2}{3}$. If the voltage developed is $V_B$ between the lower and upper side of the plane and $V_W$ between the tips of the wings then $V_B$ and $V_W$ are close to
