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 ...

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 ...

This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic materials influence and interact with current, motion, and force, making them ...

When we think of powerful magnets used in particle accelerators or for NMR (nuclear magnetic resonance), we often envision bulky machines, sometimes the size of buildings. But in an extraordinary ...

Under the right conditions, superconducting magnets allow electricity to flow essentially undisturbed, producing intense magnetic fields for a variety of uses, including nuclear fusion experiments.
