  • How To Make Magnetic Slime With Saline Solution I Heart

    Magnetic slime is one of the coolest slime recipes to make. It still oozes and stretches like slime, but with the added iron oxide powder it will react to a strong magnetic field. Ordinary magnets will not work with magnetic slime because they’re not strong enough. You have to make sure to use a neodymium magnet for the best effect.

  • How to Synthesize Ferrofluid (Liquid Magnets)

    Jun 04, 2020· Precipitate the magnetite out of the solution. Add 20 ml of PCB etchant (FeCl 3) to the green solution (FeCl 2). If you are using stock solutions of ferric and ferrous chloride, keep in mind FeCl 3 and FeCl 2 react in a 2:1 ratio. Stir in 150 ml of ammonia. The magnetite, Fe 3 O 4, will fall out of solution. This is the product you want to collect.

  • When to Use a Magnetic Stirrer in the Lab Labnet

    Nov 20, 2018· Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples. The movement of this stir bar mixes the sample thoroughly with rapid movement and agitation. The speed of the magnetic field is controlled by the user, so it can be customized to the specific sample that’s being stirred.

  • Ferrofluid Wikipedia

    Ferrofluid is a liquid that is attracted to the poles of a magnet.. A process for making a ferrofluid was invented in 1963 by NASA's Steve Papell to create liquid rocket fuel that could be drawn toward a fuel pump in a weightless environment by applying a magnetic field. The name ferrofluid was introduced, the process improved, more highly magnetic liquids synthesized, additional carrier
