Solar magnetism is a fundamental driver of dynamic phenomena on the Sun, manifesting in cyclic variations such as sunspot activity, flares, and coronal mass ejections. Central to this process is the ...

The universe is highly magnetic, with everything from stars to planets to galaxies producing their own magnetic fields. Astrophysicists have long puzzled over these surprisingly strong and long-lived ...

Certain topological materials could be used in lab tests of the dynamo effect The astrophysical dynamo effect could be tested in the laboratory using electronic materials such as hydrodynamic Weyl ...

Most planets have a magnetic field, like Earth, but with different strength or structure. It shields the planet from the energetic particles of the solar wind. The origin of the magnetic field is ...

The Earth's global magnetic field is generated in its metallic core, located nearly 3,000 kilometers beneath the planet’s surface. The field has existed on Earth for at least 3.5 billion years and ...
