The very very strong electromagnetic fields that will arise as a result, will most likely take the magnetization of any metal structure way past magnetic saturation, so that for purposes of computation, the metal structure may be neglected.

While surfactants are useful in prolonging the settling rate in MR fluids, they also prove detrimental to the fluid's magnetic properties ( specifically, the magnetic saturation ), which is commonly a parameter which users wish to maximize in order to increase the maximum apparent yield stress.

Another very common magnetostrictive composite is the amorphous alloy 3.5 13.5 with its trade name Metglas 2605SC . Favourable properties of this material are its high saturation-magnetostriction constant, ?, of about 20 magnetic-anisotropy field strength, H A, of less than 1 kA / m ( to reach magnetic saturation ).
