Weakening Magnetic Field Causing Issues for Satellites, Space Craft

We have all read about how the magnetic field of the earth protects us from the solar radiation.

The complex molten core of the Earth generates our impressive magnetic field.

The charged particle that is emitted from the sun.

Because our magnetic field is caused by the chaotic twisting and tangling of the electric current of iron in our core, the magnetic field constantly shifts its shape and position over the years.

Scientists suspect that the weakening is a warning that the Earth is moving for a polar reversal. It appears that the location of the north magnetic pole is determined by the balancing act of two massive magnetic regions plunging into the Earth right next to each other.

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

Experts made a shocking discovery - the Earth's magnetic field is reportedly weakening, and this has immediate effects.

"The challenge now is to understand the processes in Earth's core driving these changes", he said in a statement. The most critical losses in the area from Africa to South America.

One most speculated reason behind this is that there is a chance that the time for Earth's pole reversal is coming near.

Two magnetic plumes play a game of tug-of-war, with the Earth's magnetic north pole caught in the middle.

In comparison, Ciaran Beggan of the British Geological Survey told MailOnline the southern magnetic pole has scarcely changed much over the past 100 years.

After analyzing data collected by Swarm, researchers found that the strength has diminished from around 24,000 nanoteslas to 22,000 between 1970 and 2020.

What's more surprising, however, is that the phenomenon has developed and pushed westward at a speed of about 12 miles per hour. Researchers believe that this may mean that the anomaly may divide into two different cells. While this flip will not occur immediately or suddenly, and will happen over centuries, there would be multiple north and south magnetic poles during this period, all around the planet.

If the poles are in the process of reversing, Daily Mail notes that this will be happening over thousands of years, according to experts who say that it's unlikely the field to completely disappear.

The ESA warns that satellites in the area could have "technical malfunctions" because of the anomaly.

"Forecasting the future is challenging, and we can not be sure", Lead researcher Phil Livermore, an associate professor of geophysics at the University of Leeds, told Live Science.
