The Large Hadron Collider (LHC) is a giant 17-mile underground loop full of supercooled magnets, thirty-foot particle detectors, and miles of accelerator tubes. It's the largest machine that ...

Have you ever wondered how switchable magnets work? Not electromagnets, but those permanent magnet fixtures like the ones that hold dial indicators to machine tools, or the big, powerful chucks ...

These beams are controlled by the LHC's supercooled magnets. This 3D cut out shows these magnets in cross section. They operate just a few degrees above absolute zero. Two proton beams traveling ...
