This paper describes an undergraduate laboratory experiment where students study the heating behavior of magnetic nanoparticles in the presence of alternating magnetic fields. Average score on the post-test was 45±12% for students who completed the lab online, versus 43±11% for those doing the activity hands-on. Post-test scores were significantly higher than pre-tests in both sections (p < 0.05). Results also indicate that the activity contributed to outcomes set forth by ABET, Inc. for undergraduate chemical engineering students.
