This articles addresses the use of mathematics when studying the physics of electromagnetism. The authors focus on common electromagnetic concepts and their associated mathematical representation and arithmetical tools. The authors conclude that most students do not understand the significant aspects of physical situations and have difficulty using relationships and models specific to magnetic phenomenon. (less)

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy. This experiment relates to Nikola Tesla's work in electrical engineering and his invention of the AC (alternating current) induction motor. To provide learners with background about Tesla, this lesson guide suggests learners watch clips from the film "Tesla: Master of Lightning" and write a report about the challenges Tesla faced as an inventor. Use this activity to help learners explore the Law of Conservation of Energy, motors, and electromagnets. (less)

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging. Learners also explore what happens when they change the polarity of the magnet, reverse the coil, or add a clip lead to short-circuit the coils. Use this activity to illustrate how electricity and magnetism interact. The assembly of the electromagnetic swing device takes about an hour. (less)

This resource is a student tutorial on magnetism designed for beginning physical science students. It is organized into sequenced headings that each contain interactive simulations and reflective questions. The first half of the tutorial gives students a conceptual framework to understand properties of magnets and magnetic behavior. The topics then broaden to include magnetic lines of force, magnetic field, electromagnets, electric motors, and galvanometers. This resource is part of a collection developed by the Non-Destructive Testing Resource Center at Iowa State University. (less)
