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 A magnet placed just below a dish containing ferrofluid generates an array of spikes in the fluid. The magnetic attraction is strong enough to hold a magnet in place and to prevent the "fluid" from escaping when the dish is tipped. When the magnet is removed the spikes disappear and the fluid may be poured Keywords ferromagnetism, practical applications, solid state, bonding, electronic structure, periodic table, real life/environment, solids and liquids, d block, transition elements, magnetic properties From£º Data£º2005Äê4ÔÂ12ÈÕ |
