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

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven by dynamic processes deep within the planet’s core. Drawing on 11 years of ...

A UK-based research project, TomoGrav, will produce the first 3D movies of black holes, mapping plasma flows and gravity in real time using advanced AI and global telescope networks.

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

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 ...

Researchers at Paul Scherrer Institute PSI have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known ...
