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 ...

A curious topological structure known as a hopfion ring has been induced in a magnetic material. The first of its kind in 3D, the ring is a tantalizing prospect for several branches of computing ...

Scientists have observed atomic magnetic fields, the origin of magnetic forces, for the first time using an innovative Magnetic-field-free Atomic-Resolution STEM they developed. The joint development ...

“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 ...

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 ...
