Anonymous users2024-02-07Geomagnetic field refers to the natural magnetic phenomenon that exists in the interior of the earth. The Earth can be thought of as a magnetic dipole, with one pole near the geographic north pole and the other near the geographic south pole. The imaginary straight line (magnetic axis) through these two poles is tilted approximately to the Earth's axis of rotation.
The Earth's magnetic field extends tens of thousands of kilometers into space, forming the Earth's magnetosphere. The Earth's magnetosphere acts as a barrier to the Earth from charged particles carried by the solar wind. The Earth's magnetosphere is squeezed by the force of charged particles in the daytime region (sunward side) and extends outward in the Earth's nocturnal region (backsolar side).

Anonymous users2024-02-06Geomagnetic field: The magnetic field that exists in the space around the earth is the geomagnetic field. The reason why the compass (or magnetic needle) compasses north is because it is affected by the geomagnetic field.
1) The magnetic pole of the geomagnetic field: the north pole of the geomagnetic field is near the south pole of the geography; The south pole of the geomagnetic field is located near the geographic North Pole. (2) Magnetic declination:
The north and south poles of the geomagnetic field do not coincide with the north and south poles of geography, and their intersection angle is called magnetic declination, which is the earliest description of this phenomenon by Shen Kuo, a scholar of the Song Dynasty in China, and this discovery is more than 400 years earlier than the West. (3) Other matters that need to be explained in the geomagnetic field: a
The shape of the geomagnetic field is very similar to that of a bar magnet; b.If there is no influence of other magnets or iron objects nearby, the magnetic needle will always guide to the north direction when it is stationary. If you dial the magnetic needle to the east and west directions by hand, the magnetic needle will always return to the north direction of the guide.
The reason for this is due to the action of the geomagnetic field (this experiment can prove or confirm the existence of the geomagnetic field); c.Magnetic declination: From the perspective of the geographical North Pole, it is connected with the geographical north and south poles to form an "anticlockwise angle"; d.
The position of the poles of the geomagnetic field can be clearly remembered by combining the compass with the interaction between the poles.

2. The experimental results show that the measurement method of measuring the geomagnetic field with the magnetoresistive sensor has strong practicability and high accuracy.
3. The results show that the long-term change of China's geomagnetic field is a compound motion that encompasses periodical changes of different sizes.
4. Or, is there any connection between the interplanetary magnetic field and the geomagnetic field?
5. Moreover, it has ferromagnetism, can respond to ordinary magnets, and theoretically can also sense the magnetic field strength of the geomagnetic field, which may be a more ideal magnetic induction element.
A senior electrician explains what the right-hand spiral theorem is.
On the outside of the Earth, magnetic inductance lines come out of the geomagnetic north pole and enter the earth at the geomagnetic south pole. Therefore, as depicted in the diagram, the earth is round, and the magnetic inductance lines must be drawn elliptically, and the radius of curvature of the two is different. >>>More
