Goal: Gauss Meter Model X01.  Gauss meter model X01 is the hand-held device designed to meet the needs of magnetic industry to measure magnetic fields accurately, provided high-end functionality and performance in an affordable laptop instrument. Magnet testing and sorting have never been easier. Additional features including calculating magnetic field intensity versus time and displaying magnetic field direction on a Graphical User Interface on Computer.  Introduction/Background:  Magnetic fields are invisible to the naked eye but yet there is a need to detect magnetic fields for applications in manufacturing industry and research. Applications include testing of electromagnetic machinery like electric motors to see if it works correctly, or to detect magnetic field properties like mapping landscapes. A gaussmeter can use Hall Effect sensors that utilize the Hall Effect to detect perpendicular magnetic field intensity. The Hall Effect causes a voltage to be developed between two terminals on a conductor if there is a perpendicular magnetic field and a current going through the conductor. There are a range of capabilities that are present in the market for gaussmeters. A gaussmeter can be simple enough to just tell users the magnetic field intensity as a scalar or it can have many advanced features including computer linking, 3-D sensing, and measurement of AC magnetic fields.   Advisor: Professor Henry Lee.  UCI Dean's Choice Award
