THE MAGNETOSPHERE.
The magnetosphere is a strong magnetic field that surrounds our planet. Acting as a shield, it deflects most solar energetic particle radiation that emanates from the Sun.
Where does Earth's magnetic field end?
The measurements from many space missions have been combined to reveal that the Earth's magnetosphere is blown out by the solar wind into a teardrop shape. The head of the drop extends only about 10 Earth radii, or about 65,000 kilometers (40,000 miles) "upwind" toward the Sun.
How far does Earth's magnetic field reach?
The magnetic field of our planet -- otherwise known as the magnetosphere -- extends out to about 65,000 kilometers (40,000 mi) above the surface of the planet. However, that "about" part is pretty critical -- the magnetosphere isn't a fixed boundary, which always remains at exactly 40,000 miles from the surface.Aug 23, 2016
What is the magnetic field surrounding the Earth called?
Earth is surrounded by a system of magnetic fields, called the magnetosphere. The magnetosphere shields our home planet from harmful solar and cosmic particle radiation, but it can change shape in response to incoming space weather from the Sun.Feb 3, 2021
What happens if Earth loses its magnetic field?

Without it, life on Earth would be over very quickly. ... The Earth's magnetic field protects us by deflecting much of the incoming solar radiation. Without it, our atmosphere would be stripped by solar winds. We'd be bombarded with vast amounts of radiation.
Do humans have magnetic fields?
Image result
The human body naturally has both magnetic and electrical fields. Right down to the tiny cells in our bodies, every part of our body has their own field.Dec 24, 2016
