Ferromagnetic fluid
Ferromagnetic fluid - a liquid that is highly polarized in the presence of a magnetic field. In other words, when an ordinary magnet approaches this liquid, it begins to perform certain movements: it jumps up like a hedgehog, sticks to the magnet, and rises with a hump.
This ferromagnetic liquid is quite easy to make with your own hands at home.
To do this, we need oil (motor or sunflower or other) and toner (powder) for a laser printer.
All these two ingredients need to be mixed by eye until the consistency of sour cream.
For the best effect, you can heat it in a water bath, stirring, for 20-30 minutes.
But keep in mind - not every printer toner is good for magnetism. Accordingly, you need to take the best one.
All! Simple - isn't it?
