On the derivation of the terminal velocity for the falling magnet from dimensional analysis

Sobre a derivação da velocidade terminal do ímã em queda via análise dimensional

Dimensional analysis was employed to develop a predictive formula for the terminal velocity for a magnet dropped down a metallic tube. In this particular application, the technique succeeded in generating the same formula theoretically derived and that has been published by others. The analysis thus presented suggests other applications that can be developed for motivating in the use of the technique.
