The world's strongest magnet isn't just science fiction: it's real, ridiculously powerful, and used in some truly fascinating ...

As a result, ferromagnetic materials can be easily magnetized when exposed to a magnetic field. Materials like iron and magnetite, an oxide of iron (Fe 3 O 4), naturally have their magnetic fields ...

Magnetic levitation — bismuth's ability to seemingly float between two magnets — is perhaps one of the most interesting. The repulsion between bismuth and the magnets is so strong, it causes ...

The robot is powered and steered by an alternating magnetic field which is externally generated along a single axis. As the bot's two magnets are simultaneously attracted to and repelled by that ...

In a recent collaboration between the High Magnetic Field Center of the Hefei Institutes of Physical Science of Chinese Academy of Sciences, and the University of Science and Technology of China ...

Two arms run by air-powered motors rotated like propellers to measure the magnetic field as crews stepped the machine along points from one end of the cylindrical magnet to the other.

The results have been published in Advanced Optical Materials.. Second harmonic generation (SHG) is a nonlinear optical effect sensitive to symmetry breaking in materials.SHG was first seen in ...
