Optics

Magnetorheological finishing, a magnetorheological fluid-based optical cutting method, has accurate to be awful precise. It was acclimated in the architecture of the Hubble Space Telescope's antidotal lens.

If the shock absorbers of a vehicle's abeyance are abounding with magnetorheological aqueous instead of apparent oil, and the accomplished accessory amidst with an electromagnet, the bendability of the fluid, and appropriately the bulk of damping provided by the shock absorber, can be assorted depending on disciplinarian alternative or the weight getting agitated by the car - or it may be dynamically assorted in adjustment to accommodate adherence control. This is in aftereffect a magnetorheological damper. For example, the MagneRide alive abeyance arrangement permits the damping agency to be adapted already every millisecond in acknowledgment to conditions. General Motors (in a affiliation with Delphi Corporation) has developed this technology for automotive applications. It fabricated its admission in both Cadillac (Seville STS body date on or afterwards 1/15/2002 with RPO F55) as "Magneride" (or "MR") and Chevrolet commuter cars (All Corvettes fabricated back 2003 with the F55 advantage code) as allotment of the disciplinarian selectable "Magnetic Selective Ride Ascendancy (MSRC)" system) in archetypal year 2003. Added manufacturers accept paid for the use of it in their own vehicles. As of 2007, BMW articles cars application their own proprietary adaptation of this device, while Audi and Ferrari action the MagneRide on assorted models.

General Motors and added automotive companies are gluttonous to advance a magnetorheological aqueous based clamp arrangement for push-button four caster drive systems. This clamp arrangement would use electromagnets to coalesce the aqueous which would lock the driveshaft into the drive train.

Porsche has alien magnetorheological engine mounts in the 2010 Porsche GT3 and GT2. At top engine revolutions, the magnetorheological engine mounts get stiffer to accommodate a added absolute gearbox shifter feel by abbreviation the about motion amid the ability alternation and chassis/body.

As of September 2010, Acura (Honda) has amorphous an bartering attack highlighting its use of MR technology in commuter cars bogus for the 2011 archetypal year.

Magnetorheological dampers are beneath development for use in aggressive and bartering helicopter cockpit seats, as assurance accessories in the accident of a crash. They would be acclimated to abatement the shock delivered to a passenger's analgesic column, thereby abbreviating the amount of abiding abrasion during a crash
