For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

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

China might be taking some big strides into the world of science across various fields, and its latest invention is certainly no less. Researchers from the Chinese Academy of Sciences (CAS) Institute ...

“Focused” magnet system consisting of two stacked rings, each with 16 FeNdB magnet cuboids (side length 20 mm). The inner diameter is 160 mm, and the magnetic field of 20 mT exhibits a homogeneity of ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...
