Further investigation of examining students understanding of Lenz's law and Faraday's law 

written by Casey W. Sanchez and Michael E. Loverude

Magnetic induction has been known to be a particularly difficult concept in introductory physics. In this project, we build upon our previous research on probing the difficulties students have with magnetic flux in regards to Lenz's Law and Faraday's Law. This presentation will explore student responses when the format of the instrument was reversed, so that students had to use a flux vs. time graph to infer details of the physical situation. Although the newer version of the survey identifies other difficulties students have, the student responses suggest the value of this reverse process in both probing student thinking and in instruction on magnetic flux.
