A ferrofluid is made up of tiny magnetic fragments of iron put into oil. The oil helps to prevent any clumping from occurring. This particle is found in things that you may use everyday. Some of these include DVDs, CDs, radio speakers, sensors and more. Over time, this fluid will evaporate if not used. Keeping it sealed tight will help to prolong the life of the fluid so that you can use it again.
You can make your own magnet by following just a few simple steps. If you chose to purchase the liquid or fluid online, it is very expensive. If you are looking to make a ferrofluid yourself, all you will need is some magnetic ink and any oil that you may have lying around your home. Once mixed together, the ink that is near the oil will turn into a solid and become a magnetic field. It is recommended that you put the ink and oil together in a Petri dish. The fluid begins to get denser as the magnetic field becomes stronger. You should always put a plastic or latex glove on as you move your hand towards it more. You will be able to feel it getting more firm as you get closer to the magnet.
Ferrofluid is not dangerous or toxic, but it is not recommended for children to play with. Do not experiment with it around any nice things in your home and always make sure to wear old clothing that you will not mind being ruined. This fluid is very hard to wash out of anything and often causes permanent stains. You want to make sure to wear gloves and it is advised to wear some type of eye protection, such as goggles. Be sure to use dishes that are disposable in case they get close to the fluid and cause them to break.
Purchasing this fluid online can be very costly, as high as $180 for just one small bottle. If you do not want to spend that much money on this, it is recommended to get the procedures to make your own. Making your own may not be as good, but it will still do the job. The best recipe for this is to use iron-containing solutions, as steel wool does not work. Always make sure that the area that you are preparing this in is well ventilated. You can do it either outdoors or under a fume hood. This unique class of material will have you wishing you tried it sooner. You will be amazed at the nature and performance it can provide. There are some educational kits available to purchase if this is your first time and you want to make sure that you are preparing it correctly.
