Earth’s Magnetic North Pole has been shifting and this fact has been known to scientists for quite some time now. The Magnetic North Pole is not located on the geographic North Pole, located on an axis around which the planet has been revolving for eons. The Magnetic North Pole has been wandering across the Arctic Ocean towards Siberia and there are “SWARM” satellites which are monitoring the planet’s shifting magnetic field for a long time.
The European SWARM mission involves three 9-meter satellites orbiting the planet at altitudes of 300-530 km (186-330 miles) to monitor the dynamic magnetic field and also record any changes over a period of four years.
The data obtained from the Swarm satellites will help researchers get a better understanding of intricacies of the Earth’s magnetic fields. The data will help researchers to learn how the Earth’s magnetic field is affected by Solar Activity and also why large parts are getting weakened.
The Earth’s magnetic field is the security armor without which life would have been wiped out eons ago. The magnetic field of Earth has protected mankind from intense radiation from the Sun and other sources in deep space. It is very important to know exactly what makes this work.
The data which was received from the Swarm has revealed that there are weakening areas within the core-generated magnetic field spread across the western hemisphere. Some parts of the southern Indian Ocean show intensification of magnetic fields. It also confirms the fact that the Magnetic North pole is shifting towards Russia.
Rune Floberghagen, ESA’s Swarm Mission Manager said, “These initial results demonstrate the excellent performance of Swarm. With unprecedented resolution, the data also exhibit Swarm’s capability to map fine-scale features of the magnetic field.”
It is a known fact that Earth’s magnetic poles periodically reverse and the process is completed in thousands of years with the field undergoing changes which are unpredictable. However the magnetic field remains protective during these periods of changes.
