Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic materials influence and interact with current, motion, and force, making them ...

What can an exoplanet’s magnetic field teach astronomers about an exoplanet’s atmosphere? This is what a recent study published in Nature Astronomy hopes to address as an international team of ...

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the ...

Image of the Sun taken from the Solar Dynamics Observatory satellite, showing the quiet corona and magnetic structures like coronal loops, which trace the intricate patterns of magnetic field lines ...

Astronomers have mapped themagnetic field inside DR21, one of the most active star-forming regions near the Sun, and found ...

In a first-of-its-kind discovery, astronomers claim they have directly measured the magnetic fields of multiple planets beyond our solar system — potentially providing a crucial new tool in the search ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
