Eddy currents are often generated in transformers, leading to power losses. To combat this, thin laminated strips of metal are used in the construction of power transformers, rather than making the transformer out of one solid piece of metal. The thin strips are separated by insulating glue, which confines the eddy currents to the strips. This reduces the eddy currents, thus reducing the power loss.
With high-strength neodymium magnets, the effects of eddy currents become even more dramatic. These magnets are available from many scientific supply companies and the price is relatively affordable.
Eddy currents are also used to dampen unwanted oscillations in many mechanical balances. If you have access to a balance, look to see if there is a thin metal strip that moves between two magnets.
