Earth’s magnetic field is not about to reverse

A study of the most recent near-reversals of the Earth's magnetic field by an international team of researchers, including the University of Liverpool, has...

Magma ocean may be responsible for the moon’s early magnetic field

Around four billion years ago, the Moon had a magnetic field that was about as strong as Earth's magnetic field is today. How the...

New data helps explain recent fluctuations in Earth’s magnetic field

Using new data gathered from sites in southern Africa, University of Rochester researchers have extended their record of Earth's magnetic field back thousands of...

Mysterious ‘geomagnetic spike’ 3,000 years ago challenges our understanding of the...

The Earth's magnetic field, generated some 3,000km below our feet in the liquid iron core, threads through the whole planet and far into space...

Lunar dynamo’s lifetime extended by at least 1 billion years

New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic...

Nickel is crucial for Earth’s magnetic field

It only takes a simple compass to demonstrate that Earth has a magnetic field -- but it is quite difficult to explain how exactly...

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...

Geophysicist Helps Develop High-Res Map of Earth’s Magnetic Field

A University of Kentucky geophysicist is helping an international team of scientists reveal dramatic new information about the Earth's magnetic field. Two years ago, Dhananjay...

Upper part of Earth’s magnetic field reveals details of a dramatic...

Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about...

‘Quartz’ crystals at Earth’s core power its magnetic field

The Earth's core consists mostly of a huge ball of liquid metal lying at 3000 km beneath its surface, surrounded by a mantle of...

Ancient jars found in Judea reveal Earth’s magnetic field is fluctuating,...

Albert Einstein considered the origin of Earth's magnetic field one of the five most important unsolved problems in physics. The weakening of the geomagnetic...

Earth’s magnetic fields could track ocean heat

As Earth warms, much of the extra heat is stored in the planet's ocean—but monitoring the magnitude of that heat content is a difficult...

Marine sediments record variations in the Earth’s magnetic field

Past variations in the strength of the Earth's magnetic field are reflected by the production of isotopes in the atmosphere. Researchers from the CNRS,...

Uncovering Yellowstone’s subsurface mysteries

A new study providing an unprecedented regional view of the earth's crust beneath Yellowstone National Park will begin with a helicopter electromagnetic and magnetic...

Magnetic oceans and electric Earth

Oceans might not be thought of as magnetic, but they make a tiny contribution to our planet's protective magnetic shield. Remarkably, ESA's Swarm satellites...

Magnetic attraction helps explain the motion under the ocean

The EU GEOPLATE project uses magnetic sensing techniques to expand our understanding of the earth's tectonic past, while also offering tools to help locate...

Using magnetic data: Researcher uncovers 340 million year-old oceanic crust in...

A researcher at Ben-Gurion University of the Negev (BGU) has identified that the eastern Mediterranean Sea contains the world's oldest oceanic crust still in...

What did Earth’s ancient magnetic field look like?

New work from Carnegie's Peter Driscoll suggests Earth's ancient magnetic field was significantly different than the present day field, originating from several poles rather...

Ironing out the mystery of Earth’s magnetic field

The earth's magnetic field has been existing for at least 3.4 billion years thanks to the low heat conduction capability of iron in the...

Just what sustains Earth’s magnetic field anyway?

Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of...
