摘　　要：一般认为．在忽略边缘效应时，通电螺线管内部是个匀强磁场．然而，教材中所呈现出来的通电螺线管内部磁场分布图像印未能予以充分证实．本实验换用自行绕制的内径较小、长度较长的线圈进行实验，得到的实验图像较为准确地证实了这一结论．并基于真实的实验操作过程，改进了实验装置，以便更加便捷高效地得到实验数据和图像．Generally speaking, we held that ignoring the edge effect, the electrified solenoid inside is a homogeneous magnetic field. However, the current teaching materials in the electrified solenoid magnetic field distribution image has failed to be fully confirmed. In this experiment, the experiment was carried out on the coil with smaller diameter and longer length, and the results obtained from the experiment are more accurate. Based on the experimental operation process, the experiment device is improved to get the experiment data and image will become more easy and efficient.
