New Electricity and Magnetism Experiments for the Introductory Physics Laboratory

我们将物理实验室从“标准课程”改为辅导性课程，开设新的实验，强调物理概念和原理，并与同步授课课程同步授课。在过去，我们变革的第一阶段涵盖了机械学。东北大学开发了一种新的仪器，现在许多学院和大学都在使用，并已投入商业使用。我们现在处于第二阶段，电磁循环的实验。在这部分课程中，缺乏合适的、商业上可用的设备是一个众所周知的严重问题。对于安培定律和法拉第定律这样的重要概念，情况尤其如此。新的健壮而透明的实验正处于设计、原型或学生测试的不同阶段。来自国家科学基金会的支持正在被用来将它们完全纳入我们的课程，并向物理界提供它们。此外，还使用了一些设备支持，以充分满足新课程的辅导特点。

We are changing the Introductory Physics Laboratory from "standard fare" to a tutorial course with new experiments that emphasize the physics concepts and principles of, and are given in synchronism with the concurrent lecture course. In the past, the first phase of our change covered mechanics. New apparatus was developed at Northeastern which is now used at many colleges and universities, and available commercially. We are now in the second phase, the electromagnetic cycle of experiments. Lack of suitable, commercially available apparatus is a known serious problem in this part of the curriculum. This is especially true for such important concepts as Ampere's and Faraday's laws. New robust yet transparent experiments are in various stages of design, prototyping, or student testing. Support from the NSF is being used to incorporate them fully into our curriculum and make them available to the physics community. In addition, some equipment support is being used to fully satisfy the tutorial character of the new courses.
