Creative learning is discussed with respect to a specific physics topic. A teaching example, based on an apparatus that demonstrates the standard dynamo model of geomagnetism, is presented. It features many of the basic physics concepts within the syllabus of electromagnetism at high-school and university. To stimulate conceptual learning and to invite student explorations, the apparatus is designed to exhibit simplicity and transparency. Due to the connection to natural phenomena and to engineering applications it promotes a holistic view of physics. The apparatus is therefore useful for practising creative learning.
