Liquid Magnets!

Updated: Aug 28, 2019

We are familiar with hard iron magnets, but liquids can also be made magnetic. By mixing microscopic particles of metallic substances with water, for example, a liquid can be temporarily magnetic. These magnetic liquids are temporary, however. Now, chemists have found that by adding droplets of liquid plastic embedded with iron particles, a liquid can remain magnetic. You might ask why this is all so STEMazing? Liquid magnets can be steered insider the human body just like one might guide a nail with an iron magnet. If the magnetic droplets hold a particular drug or medicine, they can be steered to just the right place in the body to do their work.
