Hint: The angle of dip is perpendicular through the Earth surface at the magnetic poles. It is the angle created by the Earth’s magnetic field. It is very important because it defines the Earth’s magnetic field element.
Complete step by step answer:
The angle of dip $\left( \delta \right)$ at any place is defined as the angle create by the earth’s total magnetic field $\overset{\to }{\mathop{B}}\,$ with the horizontal direction in the magnetic meridian. It is distinctive at distinct places on the surface of the earth. The angle created with the horizontal by the Earth’s magnetic field lines is called magnetic dip, dip angle or magnetic inclination.
Let a dip needle, which is like a compass needle but swiveled horizontally so that it is free to twist in a vertical plane concurring with the magnetic meridian. It adjusts itself so that its N-pole certainly points specifically in the direction of the earth’s total magnetic field $\overset{\to }{\mathop{B}}\,$. The angle between the horizontal and the final direction of the dip needle gives the angle of dip at the given location.
The dip needle relaxes horizontally so that the angle of dip is zero at the magnetic equator. The angle of dip is very important for defining the elements of Earth’s magnetic field region. The dip needle rests vertically at the magnetic poles so that the angle of dip is $90{}^\circ $ at the magnetic poles of the earth. At all other places, the dip angle lies between $0{}^\circ $ and $90{}^\circ $.
Note: Always remember that the angle of dip is maximum at magnetic poles of the Earth and inclined vertically through the earth surface and students must note that at equator, the value of angle of dip becomes zero.
