Researchers from Hanyang University have developed an innovative micropillar array capable of collective and rapid magnetic oscillations, demonstrating strong potential for advanced applications in ...

The screws serve to conduct magnetic flux between the magnets, dragging the rotating elements along for the ride. This gearbox appears to be a refinement on [Retsetman]’s earlier design ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...
