High-field magnetic resonance imaging (MRI) machines can work better by changing the structure of radio probes from coils to antenna-like structures. How can you make an MRI scanner work properly at ...

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 ...

German physicists have overcome a long-standing limitation of magnetic field design by outperforming the famed Halbach array with a compact setup that delivers cheaper, stronger, and more uniform ...
