Snippet: Permanent liquid magnets
Description
These little magnets are made of liquid. But unlike the dancing ferrofluids you've probably seen elsewhere on YouTube, they stay magnetized even without the presence of external magnets.
A team writing this week in Science found that jamming iron-based nanoparticles at the interface of two liquids led to this characteristic. The liquid magnets can be shaped and moved by magnetic forces, electricity, and pH.
