9. IIT Patna Develops a Hybrid Magnetorheometer

Scientists at IIT Patna have developed a hybrid magnetorheometer for studying nano-iron-based magnetorheological fluids under combined compression and shear conditions.

What Are MR Fluids?

They contain magnetically responsive particles. Their viscosity can increase when they are exposed to a magnetic field.

What Does the Device Measure?

The device can test combined compression and shear and measure rheological and tribological properties.

  • The device is designed specifically to study the behaviour of magnetorheological fluids.
  • It allows testing under combined loading conditions rather than a single mechanical condition.
  • The work was supported by the Department of Science and Technology.
