The Earth's magnetic field is a lot weaker than we would expect around the island of St Helena.

Changes in the Earth's magnetic field pose a great risk to electronic infrastructure.

"We don't only look at other planets to know what's out there. It's also a way for us to learn things about the planet that's under our own feet."

Gray whales use Earth's magnetic field like a GPS to navigate their migrations, but cosmic bursts of radio static may throw them off.

Scientists have developed a three-dimensional imaging technique to observe complex behaviours in magnets, including fast-moving waves and ‘tornadoes’ thousands of times thinner than a human hair.

The Earth's early magnetic field was stronger than scientists had believed, according to ancient crystals that give researchers a view into the past.

"Don't be misled by the stats, it can happen any time, we simply don't know when and right now we can't predict when."

Researchers can control the shape of a new material called a magnetic shape memory polymer with magnetic fields, which could be useful for future robots.

The first observations from NASA's Parker Solar Probe "will fundamentally change our understanding of the sun," researchers say.

The dressing on your last salad may be a good example of what's happens with the Earth's magnetic fields.
