Destruction of chains in magnetorheological fluids by high frequency oscillation
AbstractThe results of the microscope observations of structure transitions in magnetorheological fluids under external influences are presented. Magnetic particles form chain elongated structures when applying magnetic field. These structures retain after turning off the magnetic field and even subsequent low amplitude vibration influence. It needs to demagnetize the magnetic circuit before exposing vibration for full structure destruction and initial state re-covery.
