摘　　要：装置通过STM32系列单片机作为控制芯片,对电流大小进行控制。同时利用电路简单、精度高的传统恒流源电路,反馈电路和控制电路设计出可以通过蓝牙控制的磁场发生器。For the magnetic field generator, the constant and adjustable current can be excited by a constant and adjustable magnetic field.The device uses STM32 series microcontroller as the control chip to control the size of the current.At the same time ,the traditional constant current source circuit with simple circuit and high precision, the feedback circuit and the control circuit are used to design the magnetic field generator which can be controlled by the Bluetooth.

关 键 词：磁场发生器 反馈 可调 恒流源
