This paper describes a physics laboratory activity aimed to illustrate Faraday's law in a hands-on fashion. By winding two coils of copper wire on a pen, students can construct a transformer in a short time. The induced emf in the secondary coil is observed as a function of the primary current for different waveforms. I describe how the device is constructed and show the experimental results obtained with the device. © 2005 American Association of Physics Teachers.
