Can you change the Earth's magnetic field?
NEWS: Scientists reveal evidence of an instant investment of the magnetic poles. A strange phenomenon is proof that the Earth's magnetic field can suddenly go crazy.
COMMENT: The first evidence of a reversal in the magnetic poles came in 1995 when some old well-preserved lava flows were found in the Steens Mountains in Oregon, USA Research on the rocks by a team of geologists from Occidental College in Los Angeles, revealed that the lava had an unusual magnetic pattern. These patterns are retained within the magnetic crystals in the lava, formed when it cooled, as if it were a tiny compass needles frozen in time. This finding led
very controversial and many scientists questioned the hypothesis (reversed magnetic field) for being too extravagant.

With climate change, will alter the flow of energy, by moving the reflection of the aurora borealis.
Comment: the north magnetic pole shift would be the natural manifestation of an oscillation phenomenon whose only significant result would be that the northern lights could be seen best from the south of Siberia and Europe from northern Canada and Alaska, as at present. The northern lights are formed in the uppermost layer of the atmosphere, between 70 and 150 km height from the ground.
solar activity produces reflections in space, as large amounts of ultraviolet and X-ray and energy flows. When the excited particles in the magnetosphere collide with oxygen and nitrogen, they may also plunge into Earth's upper atmosphere. These collisions, which usually occur between 40 and 200 miles above the earth, causing the hydrogen and oxygen is electrically excited and emit light. The result is a dazzling dance of green, blue, red and white known as the aurora borealis and aurora australis (northern lights and southern).
Auroras can appear as thin curtains of colored lights that are bristling at the night sky, or as blinking and diffuse bands. These are visible evidence that an electrical event is happening around the Earth in space.
the earth's magnetic fields. the sixteenth century the man sensed that the Earth behaves like a giant magnet. Since then, many more were applied to the study of terrestrial magnetism. The existence the Earth's magnetic field is known since ancient times for their applications to the navigation of the compass. In 1600, English physicist at the court of Elizabeth I, William Gilbert, published a work entitled De Magnete, considered the first treatise on magnetism. Gilbert carved a ball-shaped magnet and studied the magnetic field distribution on its surface. Found that the inclination of the field in spherical magnet coincided with what was known about the distribution of Earth's field. This experiment concluded that the Earth was a gigantic spherical magnet.
Earth behaves like a magnet. The surface magnetic field is detected because when one magnet (compass) is suspended horizontally adopts a position that their ends point roughly toward the geographic north and south poles of the axis of rotation of the Earth. The angle of deviation is called declination. The value of Earth's magnetic field is also characterized by its intensity. The intensity of a magnetic field is measured in gauss. Earth's magnetic field is quite weak, of about 0.3 gauss in the vicinity of Ecuador and 0.7 gauss in the polar regions.

It appears, that the Earth as natural magnet cooling is the result when some materials were crystallized under the magnetic influence. Indeed, the Earth contains deposits of iron ore, nickel and highly magnetic substances such magentita. We conclude that in fact the Earth is a permanent magnet, which maintains a stable magnetic field, which interacts with magnetic fields Sun and other planets, so it is very difficult to measure accurately.
