ABSTRACT:
This invention discloses a new ferrofluid and the use of ferrofluids in magnetically controllable couplings such as electromagnetic clutches and brakes. The new ferrofluid is comprised of a stable suspension of magnetizable particles having a size of at least one micron, a fluid carrier and a complexing agent. The complexing agent maintains the magnetizable particles in suspension within the carrier fluid.
