Magnetic Declination Demonstrator

Journal of Geological Education, 1955
The construction of a device to demonstrate the method of correcting a compass, so that true bearings may be read from it rather than magnetic bearings, is described. Examples are given to illustrate its use.

Magnetic Declination in Mediaeval China

Nature, 1967
THE traditional view that Christopher Columbus discovered magnetic declination on his first voyage to the West Indies in 1492 was put forward with great force by Bertelli1 towards the end of the last century and has been repeated by many since. On the other hand, Crichton Mitchell2, after having examined the evidence on which this claim was based ...

FDTD Analysis of Magnetized Plasma with Arbitrary Magnetic Declination

International Journal of Infrared and Millimeter Waves, 2007
In this paper, the frequency-dependent finite-difference time-domain (FDTD) method employing the piecewise linear recursive convolution (PLRC) scheme is applied to the numerical analysis of magnetized plasma with arbitrary magnetic declination. The PLRC-FDTD equations are derived in detail and are checked through practical examples. Excellent agreement

Vehicle detection based on magnetic declination

2008 27th Chinese Control Conference, 2008
Geomagnetic vehicle detector (GVD) is a kind of traffic monitoring equipment based on the effect that passing vehicles disturb the geomagnetic field. Having the advantages of small size, easy installation and slight damage on the road surface, GVD is to be an attractive alternative to inductive loops.

Observed magnetic declinations in West Antarctica

Journal of Geophysical Research, 1961
During the past four austral summers the United States has maintained an active oversnow and airborne traverse program in West Antarctica and on the adjoining Ross and Filchner ice shelves. Six of these traverses included as part of their objectives periodic determinations of magnetic declination D.

Tilting deviations in magnetic declinations

Terrestrial Magnetism and Atmospheric Electricity, 1929
Experiments were made by swinging compasses in a wooden swing for the purpose of investigating deviations caused by the ship's rolling motion. Results obtained with various types of compasses are submitted in two tables. Dynamic deviations, the kinetic equilibrium error, and conditions other than those considered in these two theories are briefly ...

Analytical Solution of Magnetic Declination Problem

Journal of Surveying Engineering, 1989
The magnetic declination problem involves the determination of present magnetic bearings (or azimuths) of township surveys for the purpose of retracement, based on original survey data. This paper presents an analytical solution of a problem which has been solved only graphically.
