Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...

Therefore, a magnetic field diode in which the field can only be transferred coil-to-coil in one direction should not be possible. One-way system: illustration of the diode coils set within the ...

Sometimes, the magnetic fields are relatively weak, like the ones that thread their way through the spiral arms of galaxies. Sometimes, they're medium-strength, like Earth's.

Jupiter's magnetic field is profoundly different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature study finds.

The new look at Jupiter’s magnetic field comes courtesy of NASA’s Juno spacecraft, which has been orbiting the planet since July 2016 (SN: 6/25/16, p. 16).
