The biggest benefit is that it generates the magnetosphere, which helps deflect charged particles from the Sun away from the Earth's surface.

The single biggest benefit to the Earth's magnetic field is that it shields the Earth's surface from harmful radiation.

Earth's magnet field shields humans from dangerous radiation form the sun and protects the earth's atmosphere form the solar wind. Without the magnetic field, there would be no human life on earth.
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
The Earth's magnetic field is the result of electrical currents flowing in the earth.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
Yes, the Earth has a magnetic field.
No. Earth's magnetic field does not affect its axis of rotation.
