摘要
设计了一种应用于生物电磁实验的圆柱形螺线管磁场发生装置。首先推导出螺线管产生磁感应强度的表达式,随后用Matlab对磁场进行仿真,得到磁感应强度与空间位置的关系,并设计出整套螺线管磁场发生装置。该系统由单片机产生正弦波,送至LM358放大电路放大波形后接至螺线管激励产生磁场,最后利用GM500高斯计传感器测量所产生的磁场大小。整套装置操作简单、易于拓展、调试方便,适用于许多场景。
This article introduces a cylindrical solenoid magnetic field generating device used in bio electromagnetic experiments.First,the expression of the magnetic induction intensity generated by the solenoid is derived.Then,the magnetic field is simulated with Matlab to obtain the relationship of the magnetic induction intensity and spatial position,and a complete set of solenoid magnetic field generating device is designed.This device generates a sine wave from a single-chip microcomputer,and sends it to the LM358 amplifier circuit to amplify the waveform,drives the solenoid to generate a magnetic field,and finally uses a Gauss meter to measure the magnitude of the generated magnetic field.The entire device is simple to operate,easy to expand,and easy to debug,and is suitable for many scenarios.
