How do they work?
• Externally applied magnetic field
in a direction normal to the fluid
flow direction form dipoles in the
• Magnetic poles start attracting
each others to the direction of the
field, hence forming chains
• The chains then form a skeleton
within the fluid, which gains the
fluid controllable yield stress
Why MR technology?
Mix them and you are done!
Required Materials to
synthesize an MR fluid:
• Lithium grease
General purpose oil
Micron-sized iron particles
