| Title | Unpublished paper, 'Les causes du magnétisme terrestre' [Causes of terrestrial magnetism] by Pierre Beron |
| Creator | Beron; Pierre (fl 1850) |
| Date | 1850 |
| Description | Beron considers the elements of terrestrial magnetism to be that the force with which the magnetic needle maintains its position is not everywhere the same, and that its declination and inclination vary from one region to another. These elements, he states, undergo very different modifications, which may be reduced to the following: variations with reference to the position of the sun to the south or to the north of the equator; diurnal variations in different regions of the earth; disturbances which proceed from changes of weather, and from volcanic irruptions, and those which are observed during the appearance of the aurora borealis; and secular variations.
