A permanent magnet changes the flux through coil, generating a voltage that can be read by an analog voltmeter (you can pretend it's a galvanometer). Connect the voltmeter to the coil or to the DAQ ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

— World’s First Performance Test of a High-Temperature Superconducting Coil Under Conditions Replicating the Magnetic Environment Inside a Fusion Device — Helical Fusion Co., Ltd., a world-leading ...

Round performance numbers aren't necessarily important milestones, but they do exude an undeniable aura of accomplishment. This was the case when researchers at Los Alamos National Laboratory (LANL) ...
