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 ...

An oil-soluble dye reveals how liquid magnets rotate when exposed to a magnetic field. Image Credit: Xubo Liu, Berkeley National Lab Share Scientists have always loved fiddling with the laws of ...

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 ...

A microfluidic system with channels lined with magnetic liquids can ease the flow of samples and safely transport delicate cells, possibly helping to miniaturize microfluidic devices (Nature 2020, DOI ...
