Magnetic field shield

The origin of the Earth's magnetic field is due to the movement of liquid iron in the outer core of the Earth. The liquid iron in motion conducts electric current, forming a magnetic field. The generated magnetic field interacts with the flowing charges to generate an electric field, and this cycle is maintained to produce a permanent magnetic field. The importance of the Earth's magnetic field to the Earth. As a natural protective barrier for the Earth, the Earth's magnetic field significantly reduces the impact of cosmic rays in space on the Earth. If this protective layer is missing, the solar wind may rapidly strip away the Earth's atmosphere, causing oceans to evaporate or even disappear without a trace. The strong magnetic field of the Earth protects us from harmful particle flows from the Sun, safeguarding satellites and space facilities, power networks, climate and weather, as well as human health. The survival of life on Earth largely depends on the crucial protective role of the Earth's magnetic field. Compass is a tool that indicates direction based on the Earth's magnetic field, using the correspondence between the Earth's magnetic poles and geographic poles.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The Earth's magnetic field, also known as the Earth's magnetism, is one of the physical properties within the Earth's interior. The Earth is a large magnet that forms a magnetic field around it, which is the space that exhibits magnetic force and is called the geomagnetic field. Solar storm (geomagnetic storm): Objectively speaking, solar storms are a relatively common natural phenomenon. However, if the energy and material ejected during the outbreak are massive, they will have a significant impact on the Earth's space environment such as the geomagnetic layer after reaching near Earth space, and then interfere with normal human activities. The powerful Earth's magnetic field becomes a protective shield against the solar wind and the effects of cosmic rays. The continuation of life on Earth relies entirely on the protection of this magnetic field. The functioning of a compass requires two important conditions: a magnetic needle and the Earth's magnetic field, both of which are indispensable. A magnetic needle is actually a small magnet, no matter how large it is, it can act on iron objects or charged particles that are close to the magnet. The Earth's magnetic field can help the Earth.
