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

Antiferromagnetic (AF) materials are made up of atoms or molecules with atomic spins that align in antiparallel directions of ...

The Sun's magnetic field impacts the movement of plasma on the sun's surface, but it does not actually impact the amount of heat the sun emits. Solar flares, for example, are huge explosions that ...

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 ...

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 ...

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 ...

Our protective blanket helps shield us from unruly space weather. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Earth's magnetic field — also ...

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 ...

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?
