Yes, Earth's atmosphere can be affected by changes in the magnetic field. A weakening of the magnetic field could potentially make Earth more vulnerable to solar winds, which can lead to loss of atmospheric gases over time. However, Earth's atmosphere is held in place by gravity as well, so any loss would likely occur over millions of years and not immediately.
No, an asteroid fragment would not generate a magnetic field when entering Earth's atmosphere. Its passage through the atmosphere would likely generate heat and light due to friction with the air, but it would not create a magnetic field.
You can show that the Earth has a magnetic field by looking at a magnetic compass.The north end of the compass points to the north magnetic pole, and does so everywhere on Earth. It does this by aligning itself to the Earth's magnetic field. If there weren't a magnetic field, then a compass needle would not point to any consistent direction.See related links.
As you move away from an ocean ridge, the rocks get older.
Earth's magnetic field is what allows a compass to align itself with the magnetic poles, causing the needle to point north. The magnetic field provides a reference point for navigation, helping people determine their direction relative to the Earth's magnetic field. Any changes or disturbances in the magnetic field can affect the accuracy of a compass reading.
Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.

The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
Yes evry millinium it changes

When discussing the Earth's magnetic field, we could say that the Earth has a geomagnetic north pole. The magnetic field changes every several hundred thousand years and thus the north and south magnetic poles swap places.

Earth's magnetic field is generated by the churning of molten iron in the outer core of the Earth. This generates a magnetic dynamo effect. The magnetic field acts as a shield against solar wind by deflecting charged particles from the sun, preventing them from stripping away Earth's atmosphere.
Earth's magnetic field plays a crucial role in maintaining the atmosphere by shielding it from harmful solar radiation and charged particles. This protection helps sustain life on Earth by preventing the erosion of the atmosphere and protecting living organisms from potential genetic damage. Without the magnetic field, Earth's habitability would be significantly compromised.
The auroras we see on Earth are a result of Earth's magnetic field funneling high-energy particles from the sun into Earth's upper atmosphere, where excited electrons in gas molecules create a glow. The moon has no magnetic field and no atmosphere.
