Causes of the Earth's Magnetic Field Disorder

The electromagnetic waves emitted by solar activity will cause the earth's magnetic field to be abnormal.

The propagation of electromagnetic waves conforms to the principle of linear superposition, and the propagation of one electromagnetic wave will not be affected by another electromagnetic wave that intersects with it (or exists in * * *) (they will be linearly superimposed in the area where * * * exists). Generally speaking, the geomagnetic field is a static field, which usually does not affect the propagation of electromagnetic waves. There are two main reasons for the influence of solar storm on satellite and short-wave communication. First, the electromagnetic wave spectrum generated by solar storm is very wide, which can directly enter the filtering bandwidth of communication receiver, thus affecting the received signal; Another reason is that it will have an obvious impact on the ionosphere, thus indirectly affecting satellite communication (satellite signals have to pass through the ionosphere to reach the ground) and short-wave communication using ionospheric reflection.
