Bunn (w) and
Magneto always has a few tricks up his sleeve. The old man with less raw power has to come up with inventive ways to deal with the enemy.
1.) Do Ferro Fluids exist?
2.) How do they work?
1.) YES! Ferro fluids do exist! Here a nice informative and arctic video of ferrofluids moving around.
2.) Basically, very small magnetic particles are suspended in a liquid, which allow them to move around when a magnetic force is applied. Here's a link for more information: http://education.mrsec.wisc.edu/background/ferrofluid/
