Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects ...

When everything shakes, precision is usually impossible – everybody who has ever tried to take a photo with shaky hands or make handwritten notes on a bumpy bus journey knows that. With technical ...

A ship’s steel hull becomes part of Earth’s magnetic field, which can quietly skew a magnetic compass in different directions as the vessel turns and heels. This explains how binnacle correctors work, ...

For almost a century, physicists have tried to understand why and how materials become magnetic. From refrigerator magnets to magnetic memories, the microscopic origins of magnetism remain a ...

One of the most pervasive and mysterious phenomena in the universe is magnetism. As the scientist knows it, magnetism is the invisible pull that surrounds magnets, electric currents and even the ...
