Earth's magnetic field is WEAKENING between Africa and South America, causing satellites and spacecraft to malfunction

Scientists have made a shocking discovery – the Earth's magnetic field is weakening.

The magnetic field is vital for life on our planet, as it shields us from cosmic radiation and charged particles emitted from the sun.

A large region of reduced magnetic intensity has been observed between Africa and South America, called the South Atlantic Anomaly, and it has formed a center of minimum intensity in just five years.

Researchers are speculating that the weakening is a sign that Earth is heading to a pole reversal, which is when the north and south poles switch places - and the last time this occurred was 780,000 years ago.

1. Swarm probes weakening of Earth's magnetic field


(20 May 2020 - ESA) In an area stretching from Africa to South America, Earth’s magnetic field is gradually weakening.

This strange behaviour has geophysicists puzzled and is causing technical disturbances in satellites orbiting Earth. Scientists are using data from ESA’s Swarm constellation to improve our understanding of this area known as the ‘South Atlantic Anomaly.’

Earth’s magnetic field is vital to life on our planet. It is a complex and dynamic force that protects us from cosmic radiation and charged particles from the Sun. 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. Acting as a spinning conductor in a bicycle dynamo, it creates electrical currents, which in turn, generate our continuously changing electromagnetic field.

This field is far from static and varies both in strength and direction. For example, recent studies have shown that the position of the north magnetic pole is changing rapidly.

Over the last 200 years, the magnetic field has lost around 9% of its strength on a global average. A large region of reduced magnetic intensity has developed between Africa and South America and is known as the South Atlantic Anomaly.

2. pole reversal....it would be quite a hit.

If you think about the fat that ALL electrical machinery is based on positive/negative and how current flows in ONE direction...

Maybe that would push us back to replacing carbon energy sources?
