How to Make Magnetic Slime Put a twist on the classic slime science project by making magnetic slime. This is slime that reacts to a strong magnetic field, like a ferrofluid, but it's easier to control. It's easy to make, too. Here is what you do: Magnetic Slime Materials white school glue (e.g., Elmer's glue) [...]
How to Make Liquid Magnets A liquid magnet, or ferrofluid, is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier. When no external magnetic field is present, the fluid is not magnetic and the orientation of the magnetite particles is random. However, when an external magnetic field is applied, the [...]
Magnetized Oils - Ferrofluid Oil can be magnetized in an approximately similar fashion as of magnetization of water with the exception that the oils need a longer duration of exposure to magnets in order to assimilate the beneficial properties of the latter. Oils are prepared either on the North Pole or the South Pole and [...]
