PURPOSE: A magnetic determination system of deflection yoke is provided to simplify manufacturing processes by removing a test process for an image property using a CRT. CONSTITUTION: A magnetic determination system of a deflection yoke comprises a plurality of magnetic sensors formed on an inside of a jig extended from a neck to a screen, a first and a second power sources(22,32) for generating power according to a control signal, a first and a second matrix switches(21,31) matched with the first and the second power sources respectively for generating preset switching signals, a horizontal property analysis sensor matrix(20) for driving a sensor for detecting a magnetic field generated by a horizontal deflection coil according to a switching signal applied from the second matrix switch, a vertical property analysis sensor matrix(30) for driving a sensor for detecting a magnetic field generated by a vertical deflection coil according to a switching signal applied from the second matrix switch, a first AD converter(23) for converting a magnetic field sensor signal detected at the horizontal property analysis sensor matrix to a digital signal, a second AD converter(33) for converting a magnetic field sensor signal detected at the vertical property analysis sensor matrix to a digital signal, and a data process and analysis system(60) for receiving the digital signals, determining the unbalance of coil magnetic fields, and performing data process and analysis in three dimension.
