In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...
As someone who studies materials, Lu Li knows people want to hear about the exciting new applications and technologies his ...
“Focused” magnet system consisting of two stacked rings, each with 16 FeNdB magnet cuboids (side length 20 mm). The inner diameter is 160 mm, and the magnetic field of 20 mT exhibits a homogeneity of ...
Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.
