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 [...]
Scientists 3D Printed First Ever Permanent Liquid Magnets 3D printed liquid magnets - Scientists at Berkeley Lab have created a new material that is both liquid and magnetic, opening the door to a new area of science in magnetic soft matter. Among other possible applications (such as liquid robots and even 3D entertainment), a 3D [...]
