Charles Grafton Page's Experiment with a Spiral Conductor

Abstract

In the 1830s, American experimenter Charles Grafton Page pioneered electromagnetism, developing instruments, experimental practice, and understandings that were foundational for nineteenth-century technologies such as the telegraph and induction coil. While a student, Page detected electricity in a spiral conductor where direct current had not passed and no one expected current to be. He felt bodily shock and saw sparks. This paper explores that experiment through historical accounts and my own reconstruction of it. Page opened up boundaries in the physical circuit and cultural outlook that others treated as closed. New possibilities emerged; by tolerating the ambiguity that accompanied them, Page improvised fluidly and was able to make further discoveries. In recreating his experiment, I encountered variable signals. Like Page, I developed lab techniques that generated unexpected effects and questions. This study shows how opening up physical and cultural boundaries brings to light investigative possibilities not apparent before, possibilities which can become entry points for further exploration.
