Magnetorheological Dampers for Semi-Active Suspension Control
Quick fact
MR dampers can change their damping force in less than 10 milliseconds—faster than a human can blink—by simply varying the strength of an electromagnet.
Why this is interesting
Imagine your car could make its shock absorbers softer or firmer in milliseconds. That's what magnetorheological dampers do, but how can a fluid change its behavior so quickly?
