Magnetism observed in a gas for the first time For the first time, MIT scientists have observed ferromagnetic behavior in an atomic gas, addressing a decades-old question of whether it is possible for a gas to show properties similar to a magnet made of iron or nickel. The MIT team observed the behavi...

Title: A monopole near a black hole Authors: Claudio Bunster and Marc Henneaux A striking property of an electric charge near a magnetic pole is that the system possesses angular momentum even when both the electric and the magnetic charges are at rest. The angular momentum is proportional to the pr...

Earth's north magnetic pole is drifting away from North America and toward Siberia .
After some 400 years of relative stability, Earth's North Magnetic Pole has moved nearly 1,100 kilometres out into the Arctic Ocean during the last century.
The shift could mean auroras might be more visibl...

A new study of old rocks on Earth could force a revision of theories about Mars. The results suggest ancient Mars might have been more magnetic than thought, challenging basic assumptions about the evolution of the red planet.
Data from the Mars Global Surveyor spacecraft have revealed a pattern...
