What can you do with ferrofluid?

Ferrofluid is used in rotary seals in computer hard drives and other rotating shaft motors, and in loudspeakers to dampen vibrations. In medicine, ferrofluid is used as a contrast agent for magnetic resonance imaging (MRI).

How do you make a ferrofluid science project?

Steps

1. Measure 50mL of toner in the graduated cylinder and pour it into the beaker.
2. Next, measure 30mL of corn oil and pour it into the beaker.
3. Use the stir to mix the toner and the corn oil. You want the solution to be as homogeneous as possible.
4. Now its time to experiment with your ferrofluid.

Is ferrofluid OK for kids?

(Probably not for children younger than 12) Ferrofluid allows you to actually see some of the effects of a magnetic field. There are many recipes for ferrofluid but the basic one runs about 5% magnetic solids (metal particles), 10% surfactant and 85% carrier (oil based product).

How do you make a tornado in a bottle?

Instructions:

1. Fill your container about ¾ full with clean water.
2. Add a squirt of dish soap, as well as your glitter or food coloring, if desired.
3. Seal the container tightly.
4. Move the bottle rapidly in a circular motion. After a few seconds, you should see the water begin swirling. Stop, and watch your tornado!

How do you make magnetic mud?

Instructions to Make DIY Ferrofluid (aka magnetic mud)

1. Mix the iron oxide powder into 1/4 cup of oil.
2. We mixed it a tablespoon at a time and stirred until it was completely mixed in, smooth, no clumps, but also a bit thick.
3. Drop the mud into a test tube filled with water.

Is Gold magnetic?

Gold had long been considered a non-magnetic metal. But researchers recently discovered that gold can in fact be magnetized by applying heat. Gold had long been considered a non-magnetic metal. But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.

What will happen if the magnet is cut in half?

You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

Is it safe to touch ferrofluid?

Your probably right to want to keep them out of your bloodstream if not absolutely necessary, though. However, they are considered bio-compatible and being researched for magnetic hyperthermia applications. This involves injecting them directly into your bloodstream. I’m sure touching ferrofluid is safer than smoking a cigarette.
