Correction- it's not electrical charge, it's magnetics that make it change. Ferrofluid is commonly used in speakers (particularly tweeters) as a cooling device. http://www.ferrotec.com/usa/ferrofluid_technology_overview.htm

aaah, so that's the liquid cooled you find on some of them

but why is it important for a tweeter that the liquid reacts on electricity?
