MAGNETIC FIELDS

实验目的：测定磁场中的载流导体所受的力。 实验包括测定水平悬挂于一对垂直金属丝（像一个“摆”）下方，并处于一个磁场中的载流铜 棒的洛伦兹力。当电流接通时，“摆”偏离垂直位置，并且可通过偏转的角度测定洛伦兹力的 大小。当电流通过铜棒，磁场强度和导体在磁场中的有效长度就会发生变化，并对这个效应进 行测定。 更多

在实验中： Biot-Savart定律，不同半径R的载流导体环的磁通密度B的轮廓和直导线的磁通密度被确定和讨论。   磁场传感器的位置，即到导体环平面的距离z，以及磁通密度B都是同时测量的。这是通过远程控制定位系统PS400（文章编号1023414）和磁场传感器（文章编号1021798）实现的。获得的数字数据在Coach7软件中被自动处理和可视化，因此，当传感器通过磁场时，磁通密度B(z)的剖面图会同时显示。   Biot ... 更多
