DECLINOMETER Meaning and
Definition
-
A declinometer is a scientific instrument used to measure the magnetic declination or inclination of the Earth's magnetic field at a specific location. It is primarily used by geologists, geophysicists, and navigators to determine the angular difference between true north and magnetic north, as well as to determine the angle at which the magnetic field lines intersect the Earth's surface.
The declinometer consists of a graduated scale or a digital display that indicates the measurement of the declination in degrees, minutes, and seconds. The instrument usually incorporates a compass needle or a magnetized bar that aligns with the Earth's magnetic field. By aligning the declinometer with the north-south direction, the angle of declination can be accurately measured.
Declinometers are vital tools in various fields, including cartography, surveying, and navigation. They assist in determining accurate locations and orienting maps correctly, ensuring accurate direction and heading calculations for land and sea navigation. Additionally, declinometers are useful in studying the Earth's magnetic field and its variations over time, which is important for understanding the behavior of tectonic plates, earthquakes, and volcanic activity.
With advancements in technology, modern declinometers may utilize electronic sensors or various satellite-based positioning systems to determine magnetic declination and inclination accurately. These instruments often offer more precise readings, faster measurements, and additional features, making them even more valuable in scientific research and practical applications.

Etymology of DECLINOMETER
The word declinometer is derived from two Latin roots: declinare and metrum.
1. Declinare comes from the Latin verb de- which means down or off, and clinare which means to lean or to incline. Together, declinare means to lean away or to deviate.
2. Metrum comes from the Greek word metron which means measure or measurement.
Therefore, combining these two roots, declinometer can be understood to mean instrument for measuring deviation or instrument for measuring inclination.
