A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...
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 ...
Researchers at the Paul Scherrer Institute PSI, in collaboration with the National Institute of Standards and Technology (NIST) in Boulder, Colorado, have for the first time succeeded in using ...
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?
