论文摘要
我们提出了一个简单的实验，以探索电力铁路创建的磁场，并将它们与使用易于可用信息估算的简单模型和参数进行比较。在火车上方的立交桥上行走的行人行走，并用智能手机的内置磁力计注册磁场的组件。与传输线的磁场和当地地球磁场的磁场模型相比，实验结果成功进行了比较。该实验适用于实地考察，涉及多种能力，例如对电源线的磁场进行建模，查找可靠的信息并估算不可访问的数量。
We propose a simple experiment to explore magnetic fields created by electric railways and compare them with a simple model and parameters estimated using easily available information. A pedestrian walking on an overpass above train tracks registers the components of the magnetic field with the built-in magnetometer of a smartphone. The experimental results are successfully compared with a model of the magnetic field of the transmission lines and the local Earth's magnetic field. This experiment, suitable for a field trip, involves several abilities, such as modeling the magnetic field of power lines, looking up reliable information and estimating non-easily accessible quantities.
