Ferrofluid

Ferrofluid is a magnetic liquid, that when it comes into contact with a magnet, it forms small spikes, as shown in the image below.

Ferrofluid_Magnet_under_glassI have been studying and putting to use ferrofluid for a while and I am always intrigued by it and the forms it creates. So this is why I would like to be able to use it in my final outcome, and incorporate an interactive form into it to entice audiences to engage and learn about it.

Ferrofluid_in_magnetic_fieldThere are a few downsides to using ferrofluid; as you can see from the image above, it stains surfaces very easily, leaving a horrible brown colour behind. Another downside is that the ferrofluid must not come into direct contact with the magnet, otherwise you would not be able to separate them after. However these can be solved if great care is taken, and I think it could create a very interesting installation.

This is what it looks like when ferrofluid is put onto other metal objects with the magnet next to them, and also what ferrofluid is like when it is in water. An electro-magnetic current can also be passed through magnets, so the level of current going through the magnet can be changed by altering the electricity going to it. This could be a very interesting idea what I would like to explore further before I come to my final decision on my outcome.
