Study on the Performance of the Rotating Coil Magnetometer

Abstract：

The dependence of the performance of the rotating coil magnetometer on its parameter and fabrication error is studied. The expressions of the measurement error due to the fabrication error are given. The results show that, the rotating coil magnetometer is an effective instrument to measure the field distribution of the multipole magnets, by measuring the dipole field the position ot the magnetic center of the magnet relative to the rotating center of the magnetometer can be determined, and the magnetization curve of the magnets can be measared by it also but the measurement accuracy is limited by its fabrication error.
