To start, according to tradition, we recommend watching a video from the author of the idea
What do we need:
- vegetable oil;
- iron powder;
- capacity
- magnets.
According to the author of the idea, iron powder can be obtained using a file and a piece of iron. First of all, you need to pour iron powder into the container. It is worth noting that the more powder you have, the better, since the properties of magnetic fluid are fully manifested in large quantities.
After that, add a little vegetable oil.
Mix everything thoroughly. It is better to mix with a wooden spoon or barbecue skewer.
After one and a half to two minutes of mixing, you will receive your magnetic fluid.
Note that when using it, you need to be careful not to bring the magnet directly to the liquid, since it will stick, and you can no longer remove it from the magnet. Therefore, it is advised to do this through paper, plastic or something else.
