#### Abstract

In the introductory physics curriculum, students are taught induction by examining the behavior of the current-carrying coil, which can be further reinforced by building solenoids in the instructional laboratory. This framework is then used to introduce inductors as components in electrical circuits that store energy in the magnetic field, which are utilized, for example, to build electronic filters. Whereas students often take home the idea that inductors are coils, that is not always the case. As electronic devices approach the nanoscale, one might ask a student how would it be possible to fit an inductor onto an electronic chip. In this work, we demonstrate the construction of macroscale planar spiral inductors using commercially available copper tape and compare their behavior to an off-the-shelf inductor.

#### Summary of research results to be presented

We demonstrate the use of these inductors in a series RLC circuit and observed the expected resonance behavior. The construction and testing of these inductors is a cost-effective way to introduce students to the principles behind microelectronics and electronic chip design.
