Poster Title
P-32 Constructing an Educational MRI Model Using Helmholtz Coils and Compass Oscillation to Visually Demonstrate Proton Precessions
Department
Physics
Abstract
Our goal was to make a physical model of an MRI as a teaching tool to demonstrate its physics concepts visually, as well as be manipulable for hands-on learning. We used two nested Helmholtz coils, positioned perpendicularly to each other (on providing AC, the other DC), with four clusters of compasses placed at the center. By manipulating the currents flowing through the coils and four loops of wire stationed around the contraption, we could cause the compass needles to oscillate, mimicking proton precession in MRIs. Proof of individual concepts were tested and confirmed as viable; final prototype construction in progress.
