China’s superconducting magnet hits 351,000 gauss, breaks world record
Chinese scientists at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP) have set a new world record by generating a steady magnetic field of 351,000 gauss—over 700,000 times stronger than Earth’s geomagnetic field—using a fully superconducting magnet. This surpasses the previous record of 323,500 gauss and marks a significant advancement in superconducting magnet technology. The magnet was developed through collaboration with the Hefei International Applied Superconductivity Center, the Institute of Energy of the Hefei Comprehensive National Science Center, and Tsinghua University. The breakthrough was achieved by employing high-temperature superconducting insert-coil technology nested coaxially with low-temperature superconducting magnets, ensuring mechanical stability and electromagnetic performance under extreme conditions. This achievement has important implications for accelerating the commercialization of advanced superconducting instruments such as nuclear magnetic resonance spectrometers used in medical imaging and chemical analysis. Moreover, the magnet supports critical technologies requiring strong and stable magnetic fields, including fusion magnet

The article "AC or DC: Which Is Better?" explores the fundamental differences between alternating current (AC) and direct current (DC) electricity, highlighting why homes use AC despite most modern electronic devices operating on DC. While devices like LEDs and digital gadgets require DC power, the electricity supplied to homes is AC, necessitating internal conversion from AC to DC. This situation stems from a historical debate between Thomas Edison, who championed DC, and Nikola Tesla, who advocated for AC; Tesla’s AC system ultimately became the standard due to its advantages in power transmission. Electricity is described as the flow of electrons driven by voltage, with DC providing a steady, one-directional flow, and AC causing electrons to oscillate back and forth. Although DC circuits are simpler and easier to create—illustrated by the example of a homemade battery using metals and a potato—AC is more practical for transmitting electricity over long distances. The article uses a DC toaster example to explain electrical power, resistance, and Ohm
