For the first time, scientists have created a permanently magnetic liquid. These liquid droplets can morph into various shapes and be externally manipulated to move around, according to a new study.

Magnets as we know them are always solid, but the closest thing we have to a magnetic liquid is a class of liquids called ferrofluids. Made up of iron-oxide particles suspended in liquids, these ...

The rules about what makes a good magnet may not be as rigid as scientists thought. Using a mixture containing magnetic nanoparticles, researchers have now created liquid droplets that behave like ...

Scientists have created “soft” magnets that can flow and change shape, and that could be a boon to medicine and robotics. By Knvul Sheikh Lodestone, a naturally-occurring iron oxide, was the first ...

A levitating magnetic microrobot autonomously sorts sub-millimeter particles by weight in 3D environments, enabling precise, contamination-free handling in biomedical and manufacturing applications.
