[mag‚ned·ō‚rē·ə‚läj·ə·kəl ′flü·əd]
(materials)
A low-viscosity fluid containing a suspension of micrometer-size magnetic particles that increases in viscosity proportionally to the strength of an applied magnetic field; it is used as an adaptive shock absorber for actively controlled viscous damping.

The proposed idea is based on the employment of the MR fluid in order to control the torque that is transmitted to the pump impeller.
Magnetorheological (MR) fluids are materials that respond to an applied magnetic field with a dramatic change in rheological behavior [6], An MR fluid is in a free-flowing liquid state in the absence of a magnetic field, but under a strong magnetic field its viscosity can be increased by more than two orders of magnitude in a very short time (milliseconds) and it exhibits solid-like characteristics.
This system when used with MR fluid or ER fluid has an upper hand over both passive and active types.
