Quad-cotter floating in the air by "rotating magnet" rather than "rotating wing" was created. This mechanism"Hyper loop concept" running at 1,200 km / hAlthough it does not fly high, it is also used ...

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 ...

If you want a strong magnet, the obvious answer is to buy one. However, for a variety of reasons, you might want to combine several smaller magnets. There are a few ways to do this, but the Halbach ...

Graphic 2 caption: Composite illustration of the new Halbach array magnetic field orientation setup, where the red/blue arrows indicate the magnetization direction of the individual magnets and a ...

German physicists have overcome a long-standing limitation of magnetic field design by outperforming the famed Halbach array with a compact setup that delivers cheaper, stronger, and more uniform ...
