Microtube implosions could produce megatesla magnetic fields According to the researchers who developed it at Japan’s Osaka University, the new method could be used to generate super-strong magnetic fields for fundamental research in fields such as materials science, quantum electrodynamics and astrophysics. To date, the strongest magnetic fields produced in the laboratory have been in the kilotesla (kT) range. This is far stronger than the magnetic field of the Earth, which is 0.3–0.5 × 10–4 T, and substantially exceeds the fields produced in magnetic tomography (MRI) machines (about 1 T). While fields in this lower range are important experimental tools, stronger fields could make it possible to study fundamental physics phenomena in areas such as plasma and beam physics, astrophysics and solar physics. Researchers are therefore exploring various ways of producing such super-strength fields – including collisional shocks, gamma rays and fusion in strongly magnetized plasmas, as well as explosives, high-power lasers and devices known as z-pinches, which have been used for decades by astronomers to recreate the hot plasmas that exist inside stars. Magnetic fields generated by spin currents Most of these approaches begin by taking the magnetic flux from “pre-seeded” strong magnetic fields and attempting to confine it within hollow cylindrical structures. A team led by Masakatsu Murakami has now used a similar physical configuration, but with a twist: the ultrahigh magnetic fields in its microtube implosion technique are generated by the spin currents created as charged particles are spun around by the Lorentz force, which acts on moving charged particles in a magnetic field. #einsteins #scienceexperiment #scienceeducation #scienceexperiments #scienceexpo #scienceteacher #scienceteachers #scienceisawesome #scienceresearch #scienceeducation #sciencenerd #kimia #fisika #dsr #decoding_scientific_research #education #sciencehook #teachings #chemistrylab #chemistryfacts #chemist #chemistryclass #scienceeducation #chemistrymemes #chemistry #chemistryscience #chemistrynotes (at India) https://www.instagram.com/p/CHNJhmbDh3j/?igshid=13v7s2wskkivi
