摘要
亥姆霍兹线圈产生的磁场具有广泛的物理应用。利用霍尔传感器件,自带USB2.0以及10位快速A/D的高性能单片机C8051F340,研制了单芯片(SOC)高速磁场数据测量装置,编写了磁场数据采集处理程序,设计了中心距可调的亥姆霍兹线圈,并用所研制的仪器进行了轴向磁场分布测量。结果表明,该实验装置测量精度高,实时性好,实验手段先进,可扩展为多个设计性物理实验。
The magnetic field produced by helmholtz coil is widely used in physics.By using hall sensor,we have developed a high-speed magnetic field testing system with USB2.0 interface.The software has been developed and the testing system has been designed,in which the center distance of the helmholtz coils is adjustable.The results show the instrument has high precision,good real-time character and advanced experimental methods.The instrument could be applied to many other physics experiment.
