Magnetic dip, dip angle, or magnetic inclination is the angle made with the horizontal by the Earth's magnetic field lines. This angle varies at different points on the Earth's surface. Positive values of inclination indicate that the magnetic field of the Earth is pointing downward, into the Earth, at the point of measurement, and negative values indicate that it is pointing upward. The dip angle is in principle the angle made by the needle of a vertically held compass, though in practice ordinary compass needles may be weighted against dip or may be unable to move freely in the correct plane.

Explanation:
The vertical angle between the longitudinal axis of a freely suspended magnetic needle and a horizontal line at its pivot is known as Dip. It is an important concept in the field of geology and surveying.
Dip is also known as magnetic inclination. It is the angle between the earth's magnetic field lines and the horizontal plane. The magnetic field lines are not parallel to the surface of the earth and dip at an angle towards the magnetic poles.
The dip angle varies from place to place on the earth's surface. At the magnetic equator, the dip angle is zero, while at the magnetic poles, the dip angle is 90 degrees. In general, the dip angle is higher towards the magnetic poles and lower towards the equator.
Importance of Dip:
Dip is an important parameter for navigational purposes. It is used to determine the latitude of a place by measuring the angle between the magnetic needle and the horizon. It is also used to correct compass readings and to determine the true north direction.
Dip is also used in geological mapping. It helps in determining the orientation of rock layers and geological structures. The dip angle is used to calculate the thickness of rock layers and to determine the extent of mineral deposits.
Conclusion:
Dip is an important concept in the field of geology and surveying. It is the vertical angle between the longitudinal axis of a freely suspended magnetic needle and a horizontal line at its pivot. Dip varies from place to place on the earth's surface and is an important parameter for navigational and geological purposes.
