Hi, this is Ben Roy for About.com, and today I'm going to show you how to make a liquid
magnet. Materials to Make a Liquid Magnet
You will need: * A magnetÂ
* Vegetable Oil * Laser Jet toner
How to Make a Liquid Magnet You want to pour a decent, but small amount
of toner in a glass. Be sure it's not a glass you are fond of and want to keep. Next add
a very small amount of vegetable oil. Stir the two until it's a thin consistency.
Take your magnet and put it to the glass. The solution should react to the magnetic
field of the magnet. Magnetic liquid is what's called, ferro-fluid, which is practically
oil, mixed with iron bits. The toner and vegetable oil create this.
You will see spikes because the liquid is attempting line up with the otherwise invisible
magnetic points of the magnetic field that is being created. The tension of the surface
puts limits on how far the liquid can actually reach. This creates the spike formation.
