Abstract
A precision magnetic field was generated by the NMR magnetometer and electromagnet system. The current and field feedback systems are used to control of magnetic field in the electromagnet using computer. Stability of magnetic field according to results that compare field and current feedback, current method is better than 2 times. The stability of magnetic field with current feedback improved 10 times compared with no feedback. This system is used for the calibration of magnetometers and the testing related to magnetic fields.
