Abstract:
It is a typical experiment of electromagnetic induction that a magnet falls in a nonferromagnetic metal tube.In this paper，the dynamics for the magnet is set up and solved according to simplification model.A set of drop velocity of the magnet are measured by a system consisted of Hall sensors，LED and STM32.The result is analyzed and compared with the theoretic simulation values.
Key words: drop magnet, non?ferromagnetic metal tube, induction current, terminal velocity, time constant
