Magnetic Variation Indicator

A Magnetic Variation Indicator is a type of geophysical instrument that is used to measure and display the magnetic variation or declination at a specific location. Magnetic variation refers to the angle between true north and magnetic north, and it can vary depending on the location on the Earth's surface.

The Magnetic Variation Indicator is typically used by geophysicists, surveyors, and navigators to accurately determine the magnetic variation at a given location. This information is important for various applications, such as navigation, mapping, and geophysical surveys.

In the supply group Instruments And Laboratory Equipment, the Magnetic Variation Indicator falls under the category of Geophysical Instruments. These instruments are specifically designed to measure and analyze various geophysical properties, such as magnetic fields, gravity, seismic waves, and electrical conductivity.

The Magnetic Variation Indicator is a valuable tool for professionals working in geophysics and related fields, as it provides accurate and reliable measurements of magnetic variation, allowing for precise navigation and data collection.
