opposite.
the same.
not related.
90 degrees to each other.
What is the main purpose of Earths magnetosphere (magnetic field)?
To protect Earth from radiation from solar winds.
To help keep the Earth rotating.
It creates gravity.
So that we know what direction we are going when using a magnet.
The South Atlantic Anomaly (SAA) is an irregular "dent" in the Earth's magnetic field. Why is it important for scientists to track this anomaly?
Satellites that revolve in lower Earth orbit can be damaged by radiation let in by the dent
The dent can let in radiation that can damage people and animals
The dent can cause massive storms due to the increase in radiation
Radiation let in by the dent can interfere with navigation equipment that uses magnets
