Study reveals South Atlantic magnetic anomaly is a recurring feature

In a new study, scientists from the University of Liverpool in England traced back the strange behavior of the magnetic field in the South Atlantic region and found that similar anomalies existed as far back as 8 to 11 million years ago. The South Atlantic Anomaly...

New study shows Earth's magnetic field can change 10x faster than currently believed

A new study published in Nature Communications shows that previous changes in the direction of Earth's magnetic field reached rates that are up to 10 times larger than the fastest currently reported variations of up to one degree per year. The authors combined...

Earth's early magnetic field may have been produced by its mantle, not core

A new study published in Earth and Planetary Science letters supports the concept that the Earth's early magnetic field was generated by its mantle, not its core. A new study conducted by researchers Dave Stegman, Leah Ziegler, and Nicolas Blanc provided more...

World Magnetic Model (WMM) 2020 released

A new World Magnetic Model (WMM) was officially released on December 10, 2019. WMM is a representation of the planet’s magnetic field that gives compasses dependable accuracy and one of the key tools developed to model the change in Earth's magnetic field....

Energy from Space - The Shift Has Begun

Earth and Sun's fields are weakening and we're exiting the magnetic dust cloud. At the same time, our three shields against energy from space are disappearing, we are showing increased vulnerability to space weather from our sun, and cosmic rays are already...

Earth's magnetic flip and what it means for human civilization

Earth's magnetic field has flipped many times throughout history and is now on its way toward another reversal. While the topic was highly controversial in the 20th century, numerous studies over the past decades have proven this as a fact, that it's...

Study finds Earth’s magnetic field ‘simpler than we thought’

Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1 000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not previously known. The discovery also...

A giant lava lamp inside the Earth might be flipping the planet’s magnetic field

If you could travel back in time 41 000 years to the last ice age, your compass would point south instead of north. That’s because for a period of a few hundred years, the Earth’s magnetic field was reversed. Magnetic reversals have happened repeatedly...

Highest resolution map of Earth’s lithospheric magnetic field

After three years of collecting data, Swarm mission scientists have produced the highest resolution map of Earth’s lithospheric magnetic field from space to date. The dataset combines measurements from ESA’s Swarm satellites with historical data from the...

New insight into Earth's magnetic field

NASA's new observations of the Earth's magnetic field indicate that its foreshock region is capable of accelerating electrons to almost the speed of light. Earth's magnetic field deflects the incoming charged particles from the Sun. In regions outside...

Human magnetic sixth sense breaks into mainstream science

After decades of research proved that critters across the animal kingdom on Earth can sense our planet's magnetic field, a well-known geophysicist at the California Institute of Technology (Caltech), Joe Kirschvink, has presented the first repeatable and...

Earth's magnetic field changes mapped in detail

A group of experts utilized the data collected by the ESA's SWARM satellites to show how the magnetic field is pulsating, where it's weakening and strengthening, and how fast these changes occur. For the first time, experts have mapped both the changes...

Missing link in metal physics explains Earth’s magnetic field

Earth’s magnetic field is crucial for our existence, as it shields the life on our planet’s surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth’s core. Iron is a metal, which means it can easily conduct a flow

Can humans sense the Earth's magnetism

For migratory birds and sea turtles, the ability to sense the Earth's magnetic field is crucial to navigating the long-distance voyages these animals undertake during migration. Humans, however, are widely assumed not to have an innate magnetic sense. A research...
