Solar System Magnetism
In this activity, polystyrene spheres and strong magnets are used to represent the Sun and Earth, and their distinct magnetic fields. Participants construct and use a "field detector" to predict where the magnetic fields are, and "field bits" to form loops and trace the invisible magnetic fields of the Sun and Earth. The activity is designed to be used in an informal public outreach setting. It can also be modified for use as a simple classroom demonstration. Information sheets are provided which can be printed to go along with the activity station.
