it's not just a shield. it also helps us with providing the on-earth communication

It deflects charged particles from the sun also know as solar wind. They are generated all the time and are generated in greater densities by solar flares. The magnetic field serves to deflect these particles away from the earth, and the small percentage that gets through gets redirected to the poles, where they manifest as the aurora lights (aurora borealis in the northern hemisphere). With the magnetic shielding, the earth only loses about 5 lbs of atmospheric gases to solar wind annnually. Mars, which does not have as great an iron core and hence does not benefit for a strong magnetic field, has lost almost all of its atmosphere due to the stripping effect that solar wind has on the atmosphere.

Absolutely yes..! Were it not for Earth's magnetic field we wouldn't be here because the sun blasts out high-energy particles that are lethal to life. Our magnetic field traps these particles and prevents them from reaching Earth's surface. You can often see the results with the naked eye because the so-called 'Northern Lights' are caused by those solar particles interacting with our magnetic field and atmosphere.
Scientists know that Earths magnetic field has reversed itself many times in the past (..the north magnetic pole becomes the south magnetic pole or vice versa..) This means that at some point during a magnetic field reversal it's strength is very small. During the thousands of years this condition lasts Earth would be bombarded with those deadly solar particles.

Yes. The magnetic field of Earth serves as a shield from solar winds, radiation, and some microscopic space debris. The magnetic field also serves as a compass for birds and other animals.

Yes, the magnetic field shields Earth from solar flares from the sun.

Compasses does not artwork from now on, yet different than that -- no longer a lot might exchange. The Earth's magnetic potential is fairly tiny in comparison with gravity or the different rigidity. it extremely is purely approximately beside the point.

In addition, those particles from the solar wind also regulate rain conditions, pulling opposite charged moisture together to form cloud and rain, which changes temperature of the air.

Absolutely. It deflects most of the ionized radiation that would otherwise get through.
The strength of the field is not constant, however, and when it weakens, there may be increased cancer and mutations.

Yes. It prevents the harmful radiation from the sun from killing us.

It seems to do that, it seems to deflect harmful radiation from the sun.
