Which term describes a fluid whose viscosity changes dramatically when subjected to an electric field?

Viscosity changing dramatically under an electric field is a hallmark of electrorheology. Fluids designed this way are described as electro-rheostatic (electrorheological) fluids. When an electric field is applied, polarized particles inside the liquid rearrange and form chain-like structures, which dramatically increases resistance to flow and can make the fluid behave more like a solid. This electrical-field–driven response is what sets electro-rheostatic fluids apart from others. Magnetorheological fluids respond to magnetic fields, thixotropic materials change viscosity with shear over time, and thermorheostatic systems change viscosity mainly with temperature.
