Abstract
The present invention provides a magnetic viscous fluid and a mechanical device with both improved drag force during excitation and improved rubber-resistant properties. The magnetic viscous fluid comprises a magnetic particle and base oil, wherein the base oil comprises ester base oil and non-polar base oil, and a non-polarity index of the base oil is in the range of 10 to 45.
