Abstract (English): A practical activity at laboratory associated to the course of Electromagnetism is proposed in order to determine electrical resistivity of copper, taking into account the electromagnetic induction fenomena. For this purpose, it was applyied a physical model describing the movement of a neodymium magnet through a vertical cylindrical pipe made of copper, considering the magnetic force acting on the magnet as a viscosity force. The model was numerically implemented and several simulations of the process were carried out. Direct measurements of several physical quantities such as length, thickness, mass, time and modulus of magnetic field, were required during the activity. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Se propone una práctica de laboratorio para la asignatura de Electromagnetismo, que permite determinar la resistividad eléctrica del cobre, sobre la base del fenómeno de inducción electromagnética. Para ello se utiliza un modelo físico que describe el paso de un imán de neodimio a través de un tubo cilíndrico de cobre vertical, en el cual se representa a la fuerza ponderomotriz -magnética- que actúa sobre el imán como una fuerza viscosa. El modelo fue implementado numéricamente y el proceso simulado computacionalmente. En el desarrollo de la práctica se necesita realizar mediciones directas de varias magnitudes físicas como longitud, espesor, masa, tiempo y módulo del campo magnético. [ABSTRACT FROM AUTHOR]
