Title: STATIC AND DYNAMIC CHARACTERISTICS OF ACTUATOR WITH FERROFLUID
Keywords: static electromagnetic characteristics, dynamic characteristics, electro-magnetic system, ferrofluid, finite element method, modeling.

Abstract: In this work static and dynamic characteristics of solenoid type electromag-netic actuator with ferrofluid are investigated. 3D finite element method model is de-veloped and magnetic field distribution is analyzed. Electromagnetic force is calculat-ed by Maxwell stress tensor method. Transient mode of switching on the electromagnet is modeled by system of ordinary differential equations solved by Euler method in which the time interval is divided into subintervals. The characteristics of an electro-magnet with ferrofluid are compared with these of an electromagnet without ferroflu-id. The developed models and electromagnet investigations could be used in design and optimization of new effective electromagnetic devices.
