By rotating the pulley on the Rotary Motion Sensor,
the Magnetic Field Sensor moves either toward or
away from the Field Coils. Using DataStudio and a
ScienceWorkshop interface, students can produce a
graph of magnetic field strength vs. position.
There is no need to rotate the pulley at a constant rate
as the Rotary Motion Sensor measures its position
using an optical encoder.
This graph shows the increasing magnetic field as the
sensor is moved toward the first coil, the uniform
magnetic field in between the coils, and the decrease in
magnetic field as the sensors moves beyond the second
coil.
