Experiments with eddy currents: the eddy current brake
European Journal of Physics, 2004A moderate-cost experimental setup is presented to help students to understand some qualitative and quantitative aspects of eddy currents. The setup operates like an eddy current brake, a device commonly used in heavy vehicles to dissipate kinetic energy by generating eddy currents. A set of simple experiments is proposed to measure eddy current losses

As already stressed in the previous chapters, there is a priori no difficulty in envisaging a numerical solution of the unstationary Navier Stokes equations for rotational flows: the various operators are represented by discrete systems relating the values taken by the velocity or vorticity components, pressure, density, temperature, etc...
