What Are the Effects When Solar Radiation Hits the Earth's Magnetic Field?

Earth's magnetic field is affected by solar radiation.

Solar radiation, or radiation from the Sun, is necessary for continuing life on Earth. However, when the Sun puts out more than we can use, there is an interesting, but nearly invisible, effect that takes place in the magnetic field of the Earth.

Solar Flare

This whole process occurs when a solar flare erupts on the Sun. This is a spark of increased energy that may be as large as Earth and which can last for several hours.

Solar Wind

The explosion of energy leads to the creation of solar wind. Solar wind is the effect of gases and ions caused by the solar flares pushing out from the Sun and towards the boundaries of the galaxy.

Earth's Magnetic Field

When the solar wind hits Earth's protective magnetic field, it creates a shock wave. Earth's magnetic field is compressed like a shield while the solar wind blows over it.

Polar Activity

One noticeable effect of this magnetic field compression is that as the shock wave (called a bow shock) fades, there is a generation of electricity at the north and south poles of the Earth.

Adjustment

Since a solar flare temporarily increases solar wind, once the flare is over, the wind retreats and earth's magnetic field returns to its former size.
