We discuss a sequence of experiments aimed at exploring electromagnetic induction phenomena and energy dissipation due to magnetic friction forces. We analyze the motion of a moving conductor as it passes between the poles of a permanent magnet. Motion and current-voltage sensors allow real time measurements of the position, velocity, and induced voltage. The analysis and interpretation of the results helps students construct and verify the theoretical model describing magnetic damping.

Abstract
We discuss a sequence of experiments aimed at exploring electromagnetic induction phenomena and energy dissipation due to magnetic friction forces. We analyze the motion of a moving conductor as it passes between the poles of a permanent magnet. Motion and current-voltage sensors allow real time measurements of the position, velocity, and induced voltage. The analysis and interpretation of the results helps students construct and verify the theoretical model describing magnetic damping.File in questo prodotto:
