This research studies students' functional understanding of magnetic induction, the process by which changing magnetic flux induces electrical current in a circuit. Functional understanding includes the ability to reason...

To fill the need for a tool testing introductory, undergraduates’ knowledge of basic concepts in electricity and magnetism (EM), the investigator has developed a sixty-six item, multiple-choice diagnostic exam (DEEM)....

This lesson plan contains instructions for conducting an inquiry-based lab to investigate current-carrying coils in magnetic fields. Students construct a simple galvanometer from film cannisters and other...

This activity from the Exploratorium contains an introduction to diamagnetic materials like water that are repelled by both poles of a magnet. A rare-earth magnet is used to repel grapes, whose main component is water,...

Understanding the power of magnetism on Earth isn’t always easy, and students and teachers alike will be glad to find out about this handy guide to the subject. Created by experts at NASA, this 15-page teacher’s guide...
