The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

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 ...

Thankfully for them, a team at the Vienna University of Technology has developed a method of 3D printing magnets in any form desired. First of all, though, why would anyone want an unusually-shaped ...

Researchers have mapped magnetic fields in three dimensions, a major step toward solving what they call the 'grand challenge' of revealing 3D magnetic configuration in magnetic materials. The work has ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

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 ...

When you imagine robots, you probably aren't picturing stretchy meshes that can float on water, but that's exactly what researchers at North Carolina State University have developed. These soft ...
