Elektrizität und Magnetismus – Versuch einer Differenzierung entlang sinnlicher Beobachtung
This article aims to show that sensual observations in the high voltage and high current laboratory can contribute to a differentiation and enrichment of the concepts of electricity and magnetism. The arrangement of phenomena according to qualitative aspects leads to the characterization of voltage and current as a polarity. Taking into account physical considerations, the validity of this result is also shown for the superordinate concepts of electricity and magnetism. Here an understanding of “electric current” is developed not as an electric but rather as a magnetic phenomenon. While electricity and magnetism nearly always appear mixed as electromagnetism in everyday life, their careful separation in the cognitive process is a prerequisite for the observation-based approach chosen here.
