The magnetic blocks are lights, potentiometers, switches, resistors and diodes. There are also battery blocks, and the kids can attach the parts in whatever order. I was concerned about what would happen if the kids shorted out the battery, I worried that some wires might get red hot as the power source was D cells. I later discovered that the actual power source was a current limited supply under the table attached to the battery device. The local kids science museum has an exhibit something like that.
