Researchers have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation ...

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 ...

“Focused” magnet system consisting of two stacked rings, each with 16 FeNdB magnet cuboids (side length 20 mm). The inner diameter is 160 mm, and the magnetic field of 20 mT exhibits a homogeneity of ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...

Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a permanent ...

The magnetic fields that surround some planets, such as Earth, have been recreated in miniature in the lab. The 3D model may give us a better idea of how space weather affects satellites. Any ...

Scientists have figured out a way to create and cancel magnetic fields from afar. The method involves running electric current through a special arrangement of wires to create a magnetic field that ...
