North directions on the topographic map are three in number, of which – Akhbarten

Welcome, dear visitors, to a new topic and in a new article that we are talking about, or rather we answer the following question: North directions in the topographic map, three of which I would like to present as a place of learning, a copy answer to the previous question, in order to ensure the success of your studies during this academic year This question is placed under the questions of the geographical program for the second year, the average of the second semester, 1442.

The answer to the question is: magnetic north. Magnetic north is the direction in which the compass moves north, where there is a magnetic force in the Earth’s core that creates the magnetic north and south poles. However, the shape and direction of the magnetic tilt changes from place to place on the globe and over time changes by 2.5 degrees at the same place every few hundred years. The change in Earth’s magnetic field over time may be due to causes such as dissolved minerals at depths between 2800 and 5000 km underground, as well as human labor to extract minerals and basalt rocks such as leaks. magnetic field. Discovered by the solar wind on the earth’s mantle. The origin of geomagnetism is made up of complex theories, the most famous of which is the so-called dynamo theory or generator theory, which was recently explained on the basis of the special theory of relativity, which states that the magnetic field can be conservative and occur on its own if it is important, the available quantities of thermal fluids are dispersed around the earth’s core. It is also believed that the Earth’s magnetic field is reversed every 300,000 years on average.
