Design of a Magnetic Gradient Coil with High Uniformity

Abstract:

Maxwell coil cannot meet the magnetic sensor calibration when the high uniformity of magnetic gradient is required and the space size is strictly limited. To solve this problem, a magnetic gradient coil with high uniformity was designed as magnetic sensor calibration device. Application of internal series method analyzed the magnetic field that a single axial symmetric coil generated, and then got the general characteristics of the magnetic gradient field distribution. On this basis, the structural parameters and the uniformity of magnetic gradient coil with high uniformity were calculated. Simulation analyses were carried out on the coil model and complete the design and production of magnetic gradient coil device. Finally, the data obtained from actual measurement and simulation proves the correctness of the design.
