Electromagnet Magnetic Field System
Schematic of the magnetic field control system
These devices are connected to the computer through a serial cable and then control the system through PC software in the computer. There are two main methods of control. The first is to directly control the output current of the power supply, thereby controlling the magnitude of the magnetic field strength, and the Gauss meter displays the measured value and Records in the computer for analysis; the second method is to directly set the size of the magnetic field strength through the software. At this time, the power supply will output a stable current until the magnetic field strength reaches the set value and it will stabilize. Both of these two methods provide a set of electromagnetic field systems that can be controlled and form a closed loop of the system.
