Inversion of the terrestrial magnetism in Laschamps
The prove by the image
least three places in Laschamps where the phenomenon
of inversion of the magnetism known universally
under the name "LE LASCHAMPS". At each place, corings
by the scientists of the Faculty of Geology
of Clermont-Ferrand were practised.
We are returned to that called "LA ROCHE MERLE" in the plain in the north of Laschamps.
We posed a compass to approximately 50 cm of the rock which levels, the red arrow indicates the orientation of the compass which is the real terrestrial magnetic north.
Then we posed this compass on the rock at inversion magnetic and taken the second photography where it is noted that the needle made a half-turn of almost 180 degrees before being stabilized by showing the direction opposed to the real terrestrial magnetic north.
The magnetic phenomenon of inversion can be noted at ten very specific places of 'LA ROCHE MERLE'. This place is distant from one kilometer of the two other places where this phenomemon appears, and which are close to the center of the borough of Laschamps.
Where is the 'ROCHE MERLE' ? In the north of Laschamps, the east of D68e, close to the site of the old ground of rugby of Saint-Genès-Champanelle.
