Presents an activity that explores the operation of Maglev trains. Demonstrates that elementary students can master cutting-edge technology through creating and racing magnetic vehicles on a specially designed track, researching the history of rail transportation, and exploring a current science issue. (NB)

Provides a method, using the Rowland ring as a specimen, to observe the phase transition process directly on the oscilloscope and even extract the critical exponent of ferromagnetic transition. Includes theory, experimental setup, and results. (MVL)

Reports on group conceptions of magnetism. (Author/CCM)

Electromagnetic phenomena and devices such as motors are typically unfamiliar to both teachers and students. To better visualize and illustrate the abstract concepts (such as magnetic fields) underlying electricity and magnetism, we suggest that students construct and analyse the operation of a simply constructed Johnson electric motor. In this…

Short articles describe techniques useful for junior high school science classes, including a method of filling barometer tubes, a method of tracing magnetic fields without loss of iron filings, and a technique for efficient storage and retrieval of overhead projector transparencies. (AL)

Presents a simple extension of the standard demonstration of the Meissner Effect which shows the superconductor to be a perfect conductor. (CCM)

Describes an activity that centers around advertisements for alternative medical therapy devises based on magnets. (CCM)

The Federal Aviation Administration (FAA) and its predecessor organizations, Civil Aeronautics Agency (CAA) and the Civil Aeronautics Administration (CAA) have pioneered the use of aviation education in working with schools and colleges of the nation to attain their objectives. This publication includes: a brief history of the role of aviation in…

Presents detailed teaching plans for activities with "rubberized" magnets as well as background information and alternative teaching-learning approaches. This activity may be used to develop student skills in inferring and in observing evidence of interaction. Includes instructions for equipment construction. (BR)

This guide explores the connection between electricity and magnetism with middle level and high school students. The phenomenon of electromagnetism is broken down into four lesson plans that provide students and teachers with a carefully constructed yet easy way to learn about their history. All four activities prompt students to use inexpensive,…

Discusses five experimental methods used by senior high school students to provide an accurate calibration curve of magnet current against the magnetic flux density produced by an electromagnet. Compares the relative merits of the five methods, both as measurements and from an educational viewpoint. (JR)
