Even if a plate is placed under the magnet, the magnetic mud at a certain distance from the magnet will pass through the plate and surround the magnet. When we move the magnet on the magnetic mud, we can clearly see that the magnetic mud will be adsorbed where the magnet passes, which looks like the magnetic mud moves with the magnet. I wouldn't believe anything unless I saw it with my own eyes, because such a small magnet can have such great magic.
Magnetic clay, that is, magnetic plasticine, is a magnetic toy. Generally, it is made by mixing plasticine and ferroferric oxide powder to prepare a well-ventilated workplace, because iron oxide black is a very fine powder, which does not feel good after inhalation. Remember to wear gloves and masks before you start. Take out the plasticine, heat it in your hand for a while, then stretch it into thin slices and put it on the pre-laid newspaper.
For such a big plasticine, you should use a tablespoon of iron oxide black, about 15 ml. You can roughly mix iron oxide black for your plasticine according to this ratio. Carefully put the black iron oxide powder in the middle of the plasticine board, and gently combine the edges of the plasticine to prevent the powder from scattering. Gently rubbing powder into plasticine will produce a lot of dust. After a minute of massage, plasticine will lose its original color and turn black. After blackening, knead for 3 ~ 4 minutes, and the magnetic plasticine is finished.
