Scientists have been debating over Earth's Magnetic Field for many decades w. Moreover, it is also a subject of mystery and confusion amongst people as very little is kwn about it. However, in recent years, researchers and scientists across world have started linking a phemen called South Atlantic Amaly with Earth's Magnetic Field. According to a science portal, some scientists have claimed that South Atlantic Amaly might actually lead to a reversal or a "flip" in Earth's magnetic field. Read to kw if this is true.

South Atlantic Amaly Explained

To understand possible connection between  South Atlantic Amaly and Earth’s Magnetic field, one has to understand what South Atlantic Amaly is. South Atlantic Amaly which is popularly also kwn as SAA is an area where Earth's inner zone, which contains charged energetic particles, comes closest to Earth’s surface. This peculiar phemen occurs when Earth’s surface dips down to an altitude of 120 miles or 200 kilometres. Following this action of dipping down is influx of energetic particles in this region.

Earth’s Magnetic Field Explained

Earth's Magnetic Field extends up to mind-boggling tens of thousands of kilometres into . In fact, Magnetosphere that everybody read about in ir school Geography textbooks as kids, is formed as a result of Earth's incredibly strong magnetic field. According to reports of a science portal, a paleo-magnetic study which was conducted in Australia’s red dacite and pillow basalt has estimated that Earth’s magnetic field at least 3.5 billion years old.

Is Earth’s Magnetic field about to flip?

In recent years, some scientists have been suggesting that Earth’s magnetic field is about to flip for first time in more than 700,000 years. According to reports of a science portal, if this does in fact occur, it could bring chaos in day to day life on Earth. However, some new studies conducted by University of Liverpool, England suggest that but new research from suggests that Earth’s Magnetic Field “flip” is t happening any time soon.

What brought researchers to this conclusion is an analysis y made of South Atlantic amaly, which is a magnetic “weak point” over ocean. Earlier, many researchers were led to believe that South Atlantic Amaly itself could cause reversal of Earth’s Magnetic field. But, according to reports of a scientific portal, amaly has existed for up to 11 million years. And never in past has it led to a reversal of Earth’s magnetic field.

Within area where South Atlantic Amaly occurs, protection from harmful radiation from is drastically reduced. This often causes technical malfunctions in satellites and craft that pass over or around region. Reports of a portal also claim that South Atlantic Amaly because has been around for a long time. Thus, it is a recurring feature t a symptom of impending reversal of Earth’s magnetic field. South Atlantic Amaly is a topic of debate and disagreements amongst many scientists in this field.
