This thesis present a development of an Electromagnet Pumping Device (EPD) using a ferrofluid. A moving magnetic field is used as a driving force. A loop is set up with a series of solenoids which operate sequentially to generate a moving magnetic field. The system will be controlled by an electronic circuit to achieve the sequence required to operate the electromagnets. This non conventional pump has no moving parts other than the ferrofluid and thus, it has great potentials in variety of branches of engineering. The working fluid for the system is ????0.5????0.5????2??4 .A numerical simulation were carried out to evaluate and select the proper time step for each coil afterwards. A prototype was fabricated to prove the concept.
