Jefferson Lab's Workbench Projects

Overview

The body of the magnetic field viewer is constructed from a 1/8" thick sheet of clear acrylic. 11 gauge wire is wrapped around a wooden core and then fed through holes drilled within the acrylic sheet. When an electric current is passed through the coil, a magnetic field is created that can be viewed by sprinkling iron filings on the acrylic sheet. Cores of differing materials can be inserted within the coil to see how the magnetic field is altered.
