Invited Speaker / Conférencier(ère) invité(e)

This talk will describe three new experiments recently developed for the advanced physics lab at the University of Toronto. Students work alone and have 18 class hours to complete a lab. [1] When a low viscosity fluid (in this case air) is pumped into a narrow gap between two plates filled with a more viscous fluid (here mineral oil), the resulting expanding bubble is unstable to the formation...

We experimentally demonstrate dissipative in a double pendulum system. Unlike the well-known spring coupled pendulum experiment, our experiment replaces the spring with the dissipative coupling device. Two pendulums are coupled by a device that employs Lenz's effect to dissipate energy through electromagnetic friction. To observe the influence of the dissipative coupling, we tune the natural...
