Antiferromagnetic (AF) materials are made up of atoms or molecules with atomic spins that align in antiparallel directions of ...
Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...
A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...
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 ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...
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 ...
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 ...
The new magnetic sensor is inexpensive to make, works on minimal power and is 20 times more sensitive than many traditional sensors. A team of Brown University physicists has developed a new type of ...
