Ferrofluid consist of a carrier liquid and small magnetic particles held in suspension by a surface active layer,a surfactant.The Ferrofluid can be fixed and would not flow under the external magnetic field. so we can improve the property of loudspeaker by filling the voice coil with the Ferrofluid. |

| Ferrofluid 50ml Bottle One of the most fun and interesting science experiments around. ferrofluid is a magnetic liquid that takes the shape of any magnetic field applied to it, and changes in density (it gets thicker) in a magnetic field. It''s an AMAZING tool for visualizing magnetic fields in three dimensions! With a bottle of ferrofluid and some strong magnets, you''ll be set for hours of fun experiments and demonstrations. Check out our Fun with ferrofluid page for more information and more cool images and videos of ferrofluid in action. From£º Data£º2005Äê4ÔÂ12ÈÕ |
