Abstract
This thesis describes recent progresses on the development of a new type of electromagnetic relay that has recently been demonstrated. The device is based on preferential magnetization of a permalloy cantilever in a permanent external magnetic field. Switching between two stable states is accomplished by a short current pulse through an integrated coil underneath the cantilever. The model of an electromagnetic relay is build up from the device consist of a cantilever that made from soft magnetic material called permalloy, two permanent magnets size 20x30x60mm, cantilever, a current-carrying planar coil design by CST Studio Suite and the necessary electric contact.In the other hand, this thesis describes the analysis of the magnetic behavior of electromagnetic relay component in both simulation and measurement. The simulation is being conduct via finite element analysis (FEA) using ANSYS Software while the measurement is conducted on a novel design of the electromagnetic relay.
