Magnetic levitation system is more attractive teaching tool for school education. However, it is difficult to make such a tool in junior high school and high school education, because the control theory based on state space equation is used usually, and that makes the control system too complexity. To cope with this problem, we present on-off control for magnetic levitation system. Magnet is made by using the bolt of 8x40 as iron core and winding small wire around it. The drain current flowing from field effect transistor to magnet is controlled by the voltage of gate which comes from photo transistor excited by small lamp as measuring the distance of magnet and iron ball. This system is so simple that it is possible to make as a teaching tool for magnetic levitation in every school education.

磁性悬浮系统是学校教育更具吸引力的教学工具。但是，很难在初中和高中教育中制作这样的工具，因为通常使用基于状态空间方程的控制理论，这使得控制系统过于复杂。为了解决这个问题，我们提出了磁性悬浮系统的开关控制。磁铁是通过将8x40的螺栓用作铁芯的螺栓制成的，并在其周围缠绕小线。从场效应晶体管流向磁铁的排水电流由栅极的电压控制，而门的电压来自小灯激发的照片晶体管，以测量磁铁和铁球的距离。该系统是如此简单，以至于可以作为每种学校教育中的磁性悬浮的教学工具。
