How will the weakening of the Earth's Magnetic Field affect people?

Epoch Times

The Earth's magnetic field plays a crucial role in protecting the planet from the sun's risky solar radiation.

If you are interested in astrophysics, you might have an idea about how the magnetic field of the Earth helps us in numerous ways. Recently, a weakening in the South Atlantic region of the magnetic field caused worries among scientists. However, satellites and other spacecraft flying through the area are more likely to experience technical malfunctions as the magnetic field is weaker in this region, so charged particles can penetrate the altitudes of low-Earth orbit satellites.

Scientists at the European Space Agency (ESA) are using data from ESA's Swarm Satellite to study the anomaly from the Swarm Data, Innovation and Science Cluster (DISC).

Scientists studying the phenomenon observed that an area known as the South Atlantic Anomaly has grown considerably in recent years, though the reason for it is not entirely clear. The magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 3000 km beneath our feet. If this occurs, then the north and south poles will swap positions.The European Space Agency ( ESA) was the agency responsible for the shocking discovery that collected data from the Swarm satellite array of the agency. "The challenge now is to understand the processes in Earth's core driving these changes", Jürgen Matzka, from the German Research Centre for Geosciences, said in a statement to physics.org. Currently, magnetic north aligns with the geographic north and the magnetic south aligns with the geographic south. Pole reversal is not an uncommon event and it takes place every 250,000 years. The illustration also shows how Earth's magnetic field affects the radiation in space near Earth. Their mission has three identical satellites which all offer high-quality measurements of the field in three different orbital planes, for a complete overview of the magnetic field.

"This odd behaviour has geophysicists puzzled and is causing technical disturbances in satellites orbiting Earth", the ESA said in a statement, as reported by India Today.

"The mystery of the origin of the South Atlantic Anomaly has yet to be solved", the news release said.
