The experiment of a magnet falling through a conductive tube is well-known, and teachers often use it in their classrooms, not only in high schools, but also in undergraduate courses of physics. This article describes the measurement of the thermal coefficient of electrical resistivity of a nonmagnetic metal using this experiment. At room temperature, the experiments designed by the authors are suitable for high schools. For undergraduate courses, we present a set-up with liquid nitrogen to realize the measurement over a wider range of temperatures. [ABSTRACT FROM AUTHOR] |
