超导是一种著名的现象，其中一个小钕磁铁悬浮在超导体上。然而，在磁铁上漂浮和运行的桌子大小的超导过山车很少在课堂展览中使用。而且，学生对这一现象的制作和演示也相对困难。因此，国立工业大学有明学院提出了一种简单的交互式实验系统和与使用多线圈配置控制过山车速度的方法相关的教材。该实验使学生能够通过直接体验加深对电磁学和超导性的理解，同时也让他们接触到使用“Arduino”的编程方法。本文介绍了书桌大小的超导过山车的构造方法以及用于评估它的分析方法。
Superconductivity is a renowned phenomenon, wherein a small neodymium magnet hovers on a superconductor. However, a desk-size superconducting coaster, which floats and runs on a magnet, is rarely used in classroom exhibitions. Moreover, students' production and demonstration of this phenomenon has been relatively difficult. Consequently, a simple interactive experimental system and teaching materials associated with methods of controlling the coaster’s speed using a multiple-coil configuration were proposed by the National Institute of Technology, Ariake College. This experiment makes it possible to deepen students’ understanding of electromagnetism and superconductivity through direct experience while also exposing them to programming methods using “Arduino.” This paper describes the construction method of the desk-sized superconducting coaster and the analytical methods used to evaluate it.
