Why does not the magnetic field affect the magneticrheological fluid?

01 January 1970 0 5K Report

I have made a magnetic damper so that you can see it in the form. But the effect of the magnetic field on the fluid is not very tangible. Why?

Coil number: 700 rounds

Wire diameter: 0.6 mm

Electric current: 4 amps (12 volts)

Piston and Cylinder Material: Carbon Steel

Fluid profile:

silicon oil 100cst

Carbonyl microparticles 30%
