Abstract: | Ferrofluids can also be characterized as isotropes, showing a supermagnetic behavior. The isotropic materials have magnetic properties independent of the direction of the applied magnetic field. In the absence of the external magnetic field, ferrofluids are nonmagnetic showing a magnetization in field. The size of the magnetization, M, defines an important characteristic in applications that need the ferrofluid should maintain a pressure or action of the device. The magnetization of saturation, MS, defines particularly the maximum pressure that can be produced in a fluid with applied magnetic field a higher value of MS causes the increase of the pressure exerted by the ferrofluid in a magnetic field. |
