This 30-question research-based multiple-choice test is designed to evaluate students� conceptual understanding of magnetism in algebra- and calculus-based introductory courses. The survey is based on investigations of students� difficulties in magnetism up to Faraday�s law and should be given in a 50-minute period. Statistical results have shown the survey to be reliable and valid. A summary of the construction and analysis of the survey is available in J. Li and C. Singh, <em>Developing Magnetism Conceptual Survey and Assessing gender differences in students' difficulties with magnetism</em>, 2011 PERC Proceedings, AIP Conf. Proc. <b>1413</b>, 43-46 (2012). This assessment is free for use by instructors in their classroom. However, as it takes years of development effort to create and validate reliable assessment instruments, the file is password-protected. Furthermore, the author requests that 1. students are not given copies following examination; and 2. none of the questions are incorporated into web-based question delivery systems without adequate security to prevent printing or unauthorized access by students.
