Seeking to mimic self-assembly processes that occur naturally, RIKEN researchers have demonstrated that the self-assembly of ...

For example, bringing a north pole and a north ... Iron is magnetic so the liquid iron causes Earth to have a magnetic field. The needle of a compass is a small magnet that can turn.

For example, the north polar field of Solar Cycle 24, which ended in December 2019, took nearly five years to reverse, according to the National Solar Observatory. The magnetic field flip is so ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...

The researchers placed a spectator crystal near the superconducting sample to achieve this. The crystal's optical properties change in response to the local magnetic field. This effect allows the ...
