In the blink of an eye in geological time, Canada has lost one north pole but gained another, a new and different claim to be ...

The Sun's magnetic field does impact the movement of plasma on the Sun's surface, but it does not actually impact the amount ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

Magnetars possess the strongest known magnetic fields in the universe, exceeding Earth's by a factor of one thousand trillion. The "no-hair theorem" posits that black holes only possess three ...

Physicists have found a way to circumvent a 178-year old theory which means they can effectively cancel magnetic fields at a distance. They are the first to be able to do so in a way which has ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

In the vastness of the known universe, few things are more wondrous than a magnetar. These stars are deceptively pint-sized; they squeeze multiple suns’ worth of mass into an orb no bigger than a city ...

The Earth’s magnetic field helps protect life from energetic particles that would otherwise arrive from space. Mars now lacks a strong magnetic field, and the conditions on its surface are considered ...
