QuantuMechanic: BKITU: I'm usually able to grok most of what's written in stories like this, but this one just gave me melty braining like such as andSo it's a big deal because of Maxwell's equations, and the a-symmetry between how those equations govern magnetic and electric fields. Electric fields have a non-zero divergence, so field lines may terminate at infinity. Magnetic fields have zero divergence (there are not magnetic monopoles, "magnetic charge") so field lines must terminate at their source. (forming a closed loop)I presume it is rather difficult to allow the filed lines to wrap back around and terminate on their source if you pass the filed lines through a wire ("hose") of any considerable length. Note that the length of the hose discussed in this article is 7cm.That being said, the article does reference the ArXiv post, and the authors in said post have a solid presence on the ArXiv, which means that they are at least not bat-shiat-crazy-left-fielders. However I did not check their peer-reviewed presence, so they may be just bat-shiat-crazy.

Quantum Apostrophe: QuantuMechanic: (there are not magnetic monopoles, "magnetic charge"Um, they also said man would never fly. Just keep looking, computers and technology will mean that in a few years, we'll be able to 3D print magnetic monopoles at home.

Bisu: FTA: They placed a coil at one of the tube that generated a magnetic field of 1.3 mTelsa.Only 1.3 millitelsas? Niloka Telsa is unimpressed.
Smoking GNU: I'd like to see how, as plasma usually dissipates a few centimeters from the emitter. Self contained magnetic bubble?
