This video shows a demonstration of a ferrofluid reacting to a magnet. The black liquid contains water and tiny iron particles that react to the magnet, locking together and dragging the water along with them. The spikes form along the invisible lines of magnetic force.

Can Batman's cape turn into a wing?
Scientists are currently working on developing fabrics that could be considered to have memory, AKA Memory Fabrics. With the help of MR (magneto-rheological fluids) it is a fluid with metal particles in it, and when you apply a magnetic field, they line up and become stiff. The problem is the amount they move is very small and you would need a lot of them to have any effect on your cloth.
