A variable inductor used to measure variations in terrestrial magnetism.

variometer

(ˌvɛərɪˈɒmɪtə)
n
1. (General Physics) an instrument for measuring variations in a magnetic field, used esp for studying the magnetic field of the earth
2. (Electrical Engineering) electronics a variable inductor consisting of a movable coil mounted inside and connected in series with a fixed coil
3. (Aeronautics) a sensitive rate-of-climb indicator, used mainly in gliders

var•i•om•e•ter

(ˌvɛər iˈɒm ɪ tər)

n.
1. a two-coil inductor in which electrical inductance is varied by rotating one coil within the other.
2. an adaptation of this used for detecting changes in the earth's magnetic field.
[1895–1900; vari- (see various) + -o- + -meter]

To achieve the best magnetometer (variometer) performance, it will usually be installed in a temperature-stabilized environment, either by the use of an active and magnetically clean heating-system or by selecting a highly temperature-stable location, preferably underground.

The vertical position could be kept more precise by use of the on board variometer and altimeter.
Since the three-component magnetic variometer can not be considered as a point-source instrument at a distance of 1 meter (three sensors located along a straight line, at a distance of 16 cm), the numeric value (module of vector) of magnetic induction in the coil with current could be calculated only approximately, based on the data from three variometers.
The term variometer is generally applied to any instrument that registers magnetic variations, whether it be changes in magnetic declination or any other component of the field, horizontal or vertical.
Geomagnetic data processing is carried out using Nurmijarvi (Finland) Geophysical Observatory variometer data, which is in Tartu (Estonia) Observatory.
Artificial neural network performs functions corresponding to total energy variometer functions.
These state- of- the- art gliders will be equipped with a Global Positioning System ( GPS) and a Variometer so that a commando can adjust his rate of ascent or descent.
As a general rule of thumb, for most small airplanes, when against a headwind or a downdraft, you should increase glide speed by half the headwind component (and if you had a variometer, also by four to five knots per 100 fpm of sink).
To be properly equipped, participants should also wear an emergency parachute and carry a map and variometer which charts rates of ascent and descent as well as height.
