Another severe crisis has arisen before the world in the Corona period. Surprising scientists have revealed that the Earth’s magnetic field is weakening. The magnetic field is very important for life on earth. It is because of the magnetic field that the Earth can escape from the radiation from the space and charged particles emanating from the Sun. Now this magnetic field has started to weaken. Let us know what is this crisis and what is the threat to satellites and spacecraft …
The area between Africa and Latin America is decreasing
Scientists have discovered that the intensity of the Earth’s magnetic field has decreased over a large area between the continent of Africa and Latin America. This is called South Atlantic asymmetry. About five years ago, this area of low intensity has developed. Scientists predict that the Earth is undergoing a change in poles. Under this, the North Pole and the South Pole take the place of each other. The last time this happened was 7,80,000 years ago.
Serious crisis hovering over satellites and spacecraft
The South Atlantic asymmetry poses a serious crisis for satellites and spacecraft passing through this region. The satellites and spacecraft that are traveling in space are falling prey to technical glitches. This entire crisis has been exposed by the European Space Agency. The agency has collected its data with the help of its satellite. These satellites are specifically designed to identify and measure the magnetic waves producing the Earth’s magnetic field. This gave scientists information about the decrease in the Earth’s magnetic field.
The magnetic field is decreasing rapidly near Africa
The European Space Agency has been studying the Earth’s magnetic field since 2013. The mission has three satellites that provide high-quality data. German researcher Jürgen Matzka said that South Atlantic asymmetry occurred in the last decade and is now growing very rapidly. We are fortunate that there are swarm satellites in space that investigate the South Atlantic asymmetry and give statistics. The challenge now is to understand this whole process which is being promoted from the core of the earth.
Changes happen in 2,50,000 years
For the last few years there was a decrease in the magnetic field on the radar of the experts. Magnetic field intensity has decreased by 9 percent in the last 200 years. In the meantime, the magnetic field has decreased more recently in a large part between Africa and South America. Scientists said that the change in poles does not happen suddenly and it happens slowly. This change occurs every 2,50,000 years.
Know why the Earth’s magnetic field is important
Earth’s magnetic field is like a shield for life. According to geologists, the origin of this magnetic field is due to the electric currents flowing in the iron-rich fluid outer core of the Earth. It is believed that the Earth’s magnetic force is like a giant rod magnet. In addition to ‘geographic north-south poles’, there is another pair of poles ‘north and south magnetic poles’ in the earth. This region bends the charged particles of the Sun coming to the Earth. Without the magnetic field, the charged particles of the sun will penetrate the ozone layer and come to Earth. This will increase the risk of UV radiation.
