How To Make
Ferro Fluid
Ferro fluid is a type of liquid magnet that becomes strongly
magnetized when in the presence of a magnetic field.After the Second World War,
Japan imitated western wholesale
electronics distributor like televisions, portable radios, cars, etc.
Composed of a colloidal mixture of magnetic particles, the typical ferrofluid or
liquid magnet is made up of about 5 percent of magnetic solids, 10 percent of
surfactant, and 85 percent of a liquid agent referred to as the carrier. These
liquid magnets have become extremely popular in the production of speakers,
laser heads, and computer disk drives, as they are not magnetic unless there is
an external magnetic field present. If you would like to make your own
ferrofluid, it is possible to do so at home with the right safety
considerations, materials, and instruction.Sex

their size penile in the length and the perimeter.So if one has tried many
options for losing weight but nothing really worked among these various Weight
loss capsule she must go for Rimonabant, Phentermine and Acomplia’s
consumption.
Safety Considerations
The process of making a liquid
magnet involves using flammable substances that will generate toxic fumes and
heat. Because of this, you should be sure you wear protection over your skin and
your eyes and perform your work in an area that is well ventilated. Like always,
keep the materials used for producing ferrofluids out of reach of children and
pets.
Materials Needed
To make your own ferro fluid you can use
common materials that can be found at your local retailers and pharmacies. The
two most important ingredients needed are oleic acid and PCB etchant. Oleic acid
can be found in local pharmacies and PCB etchant, also referred to as ferric
chloride solution, can be found in a larger electronics store. In addition to
these two substances, you will need household ammonia, steel wool, distilled
water, a magnet, kerosene, a heat source, 2 beakers, a plastic syringe, and
filter papers.
Once you find all of the ingredients you need to make
your ferrofluid or liquid magnet, you will need to find detailed procedures on
how to synthesize magnetite. This is the first step in preparation for making
ferrofluids. An accurate guide will give you the measurements of solutions and a
step-by-step process of how to combine the solutions and synthesize
magnetite.Once you have synthesized the magnetite, you will then need to find
steps on how to suspend the magnetite in your liquid carrier agent. You must
ensure the magnetic particles are coated with a surfactant so that they will not
stick together when they are magnetized. This process must be followed step by
step to ensure the final product comes out right.
Making ferrofluids can
be a fun activity or a wonderful chemistry project.Make sure that you get your
wooden hangers from
a good manufacturer so that they do not have sharp edges or seams that can snag
and tear your clothing or merchandise. If you are looking for a unique
experiment to perform for your chemistry class,Use pant hangers in your home or retail store
to make a really good impression. consider producing your own ferrofluid. Float
a penny over the ferrofluid and explore the shapes you can make using a hard
magnet and have an enjoyable experience learning about science and the elements.
