Description

Technical Field [0001] The present invention relates to a natural remanent magnetization

The present invention relates to a natural residual magnetic visualization apparatus.

The geomagnetic field is a magnetic field formed around the earth. It surrounds the outside of the earth centered on the north magnetic pole and south magnetic pole in the north pole as if there is a large magnet inside. It is because of the influence of the earth magnetic field that the compass is pointing to the self and the magnetic north everywhere.

It is also known that the Earth's magnetic field protects life on earth by blocking high-energy particles coming from the sun and space into the earth, and it also affects the formation of earth's surface.

The effect of the geomagnetic field on the formation process of the earth's surface can be easily seen through the phenomenon that occurs in the formation process of the rock.

When a rock is formed, minerals with a magnetic component contained in the rock are magnetized to the direction and magnitude of the earth's magnetic field, and this phenomenon is called natural remnant magnetism.

Natural residual magnetism contains crystals or particles that are magnetized inside when the rock is ejected from the gap of the crust into a molten state to form magma or lava. At first, due to the high temperature, magnetic crystals and particles are magnetized It is not fixed but exists in a random direction.

However, when the magma or lava cools down to a temperature lower than the Curie temperature, the internal magnetic component becomes magnetized, and is hardened in the same direction as the geomagnetic field due to the influence of the geomagnetic field.

Since the geomagnetic field changes its direction and size during the geological period, it can predict the time of formation of the rock by confirming the direction and magnitude of the natural residual magnetism formed in the rock, and it is an important clue to understand the movement of the crust using this.

Thus, the geomagnetic field can understand the existence of the magnetic field through the natural residual magnetism formed on the rock, and it has important meaning to provide information about the formation of rock or the movement of crust.

Therefore, research has been conducted on devices that can visualize the earth's magnetic field and induce understanding of it.

For example, Korean Patent No. 10-0668370 discloses a device for visualizing a geomagnetic field of a geomagnetic field by forming a measuring part formed along a meridian band of a global model, and measuring a declination angle and a dip angle of the geomagnetic field.

However, the apparatus has a problem that it can not visualize the formation process of the natural remnant magnetism of the rock formed by the earth's magnetic field, only to understand the difference between the magnetic field on the earth and the magnetic north, the north pole, the south pole, and the south pole .

As described above, among the devices that understand and visualize the geomagnetic field, there is a lack of research on devices capable of explaining and understanding natural residual magnetism formed in rocks.

Therefore, it is necessary to study the device that can easily understand the earth magnetic field through natural residual magnetism and explain it through visualization.
