The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly ...

Norm First conceived of by Igor Tamm and Andrei Sakharov in the 1950s, tokamaks use a toroidal magnetic field to contain the hydrogen plasma to help keep it at the sun-like pressure and ...

Magnetic fields in the halo of the Milky Way have a toroidal structure, extending in the radius range of 6000 light-year to 50,000 light-year from the Galaxy center. The Sun is at about 30,000 ...

The magnetic field for such a transformer is almost totally ... and the transformer can be very efficient. The toroid itself is made of special material. They are usually formed from powdered ...

This motion generates Earth’s magnetic field, but not uniformly ... particularly in a toroidal region that starts about 400 miles above the surface. In the SAA, this protective function is ...

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery ...

Despite our cosmic connection with the sun, there are still numerous scientific mysteries to unravel about this critical star, particularly its magnetic field. “The sun is not just off in some v ...

Now, a new study, published Wednesday in the journal Nature, reveals loggerhead turtles, the most abundant sea turtle species nesting in the United States, learn the magnetic fields of specific ...
