Apparatus for investigating resonance with application to magnetic resonance imaging. American Journal of Physics, 83(11), 942-947. doi:10.1119/1.4928177Resonance is typically studied in the context of either a pendulum or a mass on a spring. We have developed an apparatus that enables beginning students to investigate resonant behavior of changing magnetic fields, in addition to the properties of the magnetic field due to a wire and the superposition of magnetic fields. In this resonant system, a compass oscillates at a frequency determined by the compass's physical properties and an external magnetic field. While the analysis is mathematically similar to that of the pendulum, this apparatus has an advantage that the magnetic field is easily controlled, while it is difficult to control the strength of gravity. This apparatus has been incorporated into a teaching module on magnetic resonance imaging. (C) 2015 American Association of Physics Teachers.This Item is protected by copyright and/or related rights.
