Helmholtz Coil Base

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.
