NASA monitors the South Atlantic Anomaly, a growing magnetic field disturbance affecting satellites and spacecraft.

It is known that the thermoelectric efficiency of some materials can be considerably enhanced in a magnetic field (examples are bismuth-based alloys which are used for low-temperature refrigeration).

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...

it produces its own magnetic field the magnetic field cannot be turned on and off - it is there all the time Bar magnets and horseshoe magnets are examples of permanent magnets. An iron rod placed ...

The radiation of high-energy protons in the South Atlantic Anomaly can cause a satellite, such as the International Space ...

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...

Though you might think that compasses will always point towards the geographic north pole, the magnetic and geographic poles ...
