Magnetic Field of Earth Weakening a Sign Poles Are Flipping

magnetic field

The magnetic field of Earth is weakening more rapidly than many scientists thought it would, a sign that Earth’s magnetic poles might flip within a few hundred years as opposed to thousands of years. Data collected from Swarm, the collective name for three European Space Agency (ESA) satellites, confirms that Earth’s magnetic field is weakening, something which has led to many past switches in Earth’s magnetic poles.

According to LiveScience, the magnetic field of Earth is produced by an iron core at the center of the planet and it extends above Earth’s surface 370,000 miles. One of the reasons that Earth’s magnetic field is important is that it is like a defensive force field, blocking out much of the radiation bombarding Earth daily from space and the sun.

Deep ocean core studies have confirmed, according to NASA, that the Earth’s magnetic poles reverse on a relatively frequent basis. They usually switch anywhere from 200,000 to 300,000 years. As it has been 700,000 years or so since a flip has taken place, Earth is overdue for one. The weakening magnetic field might be a sign that the switch will occur sooner, rather than later.

Scientists, according to a report by LiveScience, had thought that Earth’s magnetic field was weakening by about five percent every hundred years. At that rate, they calculated that a flip in the Earth’s magnetic fields would not happen for around another 2,000 years.

However, the new data from Swarm indicates that Earth’s magnetic field is actually currently weakening at a rate of five percent every decade instead of century. That rate is 10 times faster than the scientists had allowed for in their calculations about when the next flip would happen.

The biggest amount of weakening in the magnetic field is over Earth’s Western Hemisphere. Though the magnetic field has become somewhat stronger in a few regions, for example over the southern Indian Ocean, that strengthening has not been powerful enough to offset the weakening in it elsewhere. The weakening of the overall magnetic field of Earth is a sign that the poles are slowly in the process of flipping.

According to the observations made by Swarm, the switch or flip of Earth’s magnetic poles is already underway. Magnetic north is slowly headed to the south, in the direction of Siberia. Still, the switch will “take many hundred if not a few thousand years,” as Swarm’s mission manager, Rune Floberghagen, stated in an interview with LiveScience.

While past switches of Earth’s magnetic poles have not resulted in signs of radiation damage to life occurring or mass extinctions, Earth’s weakened magnetic field will let more radiation than normal get through the protective barrier. This could result in disruptions to the world’s communications networks and power grid.

Other information is also collected by the three Swarm satellites, about Earth’s oceans, ionosphere, crust, mantle and core. The data that the satellites are gathering could lead to improvements in locating natural resources, predicting earthquakes and improving navigation systems.

Though the data from the three satellites known as Swarm shows a definite weakening of Earth’s magnetic field over even just the past few months, a complete flip of Earth’s magnetic poles will still likely not occur for at least around a couple of hundred years, according to LiveScience.

Earth’s magnetic field is weakening rapidly now, a sign that the poles are in the process of flipping. Whenever the shift of the magnetic poles is complete, the planet’s magnetic field will presumably be as strong as it ever was and will continue to protect the planet’s life from radiation. The three ESA space satellites, known as Swarm, have collected data that indicates the planet’s magnetic field is weakening at a faster rate than it has been. This is not a sign that the end of the world is eminent, however, even if the flip happened at a much faster rate, such as within a decade, according to

    I have discovered that intelligent real estate agents everywhere you go are getting set to FSBO Advertising. They are knowing that it’s not just placing a sign in the front yard. It’s really in relation to building interactions with these sellers who at some time will become customers. So, once you give your time and effort to supporting these suppliers go it alone – the “Law involving Reciprocity” kicks in. Thanks for your blog post.

    As far as scientists can tell, the earth has had a magnetic field for billions of years. The ancient Chinese were likely the first to discover the field’s effect on lodestones, although Europeans may not have figured it out till the Middle Ages.

    islam is right

    Fellow humans, another scientific knowledge has again proven the words of the Holy Quran , if you are not a Muslim become one now and if you are a Muslim it’s time to repent . When the sun rise from the west your repentance will no more be accepted which means you are bound for hell fire in the next life and forever .

    This cirtifies that the records of islamic and other old puranas are true

    This means the sun will rise from the west which corresponds to Islam

    I have a question is the southern pole was the northern one in the past and the opposite? Was the sun rais from the west??

    We shall see when the next six month set of data are published, whether the poles ate shifting polarity. So far, only the Northern magnetic pole is migrating extensively. And only one magnetic pole on the sun has changed polarity on its cycle which had been regular since we began measuring it. As far as weakening goes, the last time the sun entered a cycle like this one we had the Carrington Event, a solar flare which burned the major electrical system of the day, the telegraph. With our field weaker this time, a less powerful flare could burn out our major grids, sending us back to the 1880’s. Instead of installing circuit breakers into our grid, our governments are wasting billions on carbon dioxide reduction.
