NASA has reported that a strange dent in the Earth's magnetic field is splitting in half.


The Earth's magnetic field has a weak spot that is located over South America and the Atlantic Ocean. It is known as the South Atlantic Anomaly (SAA).


The South Atlantic Anomaly is an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface, dipping down to an altitude of 200 kilometres.


The effect is caused by the non-concentricity of the Earth and its magnetic dipole.


While there will be no impacts at a ground level, satellites passing through the area must account for extra radiation.


The magnetic field inside the Earth is also changing.


The Earth's magnetic field protects us from harmful rays from the sun.
