利用磁传感器研究通电螺线管中心轴线上的磁场与位置、电流之间的关系,分别得到B-x图象和B-I图象,并得出实验结论。然而,实验仍存在通电螺线管电流强度较小、当手持磁传感器操作时,磁场方向没有严格沿着探头轴线方向等不足,因此,应增加螺线管匝数,保证磁传感器在螺线管的中心轴线上,从而得到更精确的实验结论。
Using magnetic sensors to study the relationship between the magnetic field on the central axis of the electromagnetism solenoid and its position and current, B-x images and B-I images were obtained respectively, and the experimental results were obtained. However, there is still a small current intensity of the solenoid. When the handheld magnetic sensor is operating, the direction of the magnetic field is not strictly along the axis of the probe. Therefore, the number of turns of the solenoid should be increased to ensure that the magnetic sensor operates in the solenoid The center axis, so as to get more accurate experimental conclusions.
