Give information about the Earth’s magnetic field lines and the location of the magnetic poles.
The magnetic field lines of the Earth resemble that of a magnetic dipole located at the centre of the Earth.
The axis of the dipole does not coincide with the axis of rotation of the Earth but is presently tilted by $11.3^{\circ}$.
The magnetic poles are located where the magnetic field lines due to the dipole enter or leave the Earth.
The location of the north magnetic pole is at a latitude of $79.74^{\circ} \mathrm{N}$ and a longitude of $71.8^{\circ} \mathrm{W}$, a place somewhere in north Canada.
The magnetic south pole is at $79.74^{\circ} \mathrm{S}, 108.22^{\circ} \mathrm{E}$ in the Antarctica.

A dip circle is adjusted so that its needle moves freely in the magnetic meridian. In this position, the angle of dip is $40°$. Now the dip circle is rotated so that the plane in which the needle moves makes an angle of $30°$ with the magnetic meridian. In this position the needle will dip by an angle
