Abstract
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.

Esta tesis presenta el desarrollo de un dispositivo de bombeo usando electroimanes (EPD), la cual produce movimiento de un ferrofluido debido a un campo magnético móvil. Un lazo es configurado con una serie de solenoides que operan de forma secuencial a fin de generar un campo magnético móvil en torno al lazo. El sistema es controlado por un circuito electrónico que realiza la secuencia requerida para operar los electroimanes. Esta bomba es diseñada sin ninguna parte móvil, más que el fluido mismo, por tanto, podría tener una gran variedad de aplicaciones potenciales en ingeniería. El fluido de trabajo para el sistema es ????0.5????0.5????2??4. Simulaciones numéricas fueron realizadas para evaluar y seleccionar el paso del tiempo apropiado para cada bobina. Luego, se construyó un prototipo para probar el concepto.
