Product Details

AP Physics 2, Big Idea 2, Investigation 6

Our present-day understanding of the laws of nature are intertwined with a deep understanding of field theory. All four fundamental forces are exerted “at a distance,” and fields existing in space for each force allow us to explain how these forces interact. A balloon is attracted to a sweater when rubbed by the sweater, but how do we explain and visualize this attraction?

This advanced-inquiry lab begins with an introductory activity that familiarizes students with mapping equipotential lines of a dipole charge setup. Next, guiding questions lead students to map out the field lines themselves and to consider various potential setups that would produce different electric field configurations. This lab uses high-quality conducting ink pens and greatly enhances students’ understanding of an abstract and difficult concept.

Complete for 24 students working in pairs. Multimeters and power supplies are required and available separately.
