Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

There are currently several superconducting materials used for design and fabrication of high-field magnets. 1 The most widely established of them—low-temperature superconductor NbTi—is the workhorse ...

The magnetic field swirling around an enormous black hole, located about 55 million light-years from Earth, has unexpectedly switched directions. This dramatic reversal challenges theories of black ...
