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 ...

An international research team led by DTU has developed a new magnetic material that features a stable internal magnetic structure, almost no external magnetic field, and retains these properties ...

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 ...

Researchers at the National High Magnetic Field Laboratory in Tallahassee, Florida, have pushed a palm-sized superconducting coil to 42 tesla, placing a device small enough to hold in one hand within ...

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.

A magnet small enough to fit in the palm of your hand can match the strength of some of the world’s most powerful magnets for the first time. But superconducting magnets that produce strong magnetic ...
