Small groups investigate the interaction between a coil of wire and a magnet to create an electromagnetic field and observe the voltage they create. Through further interactions, they realize a conductor can be charged from the electromagnetic field.

Instructional Ideas

• Have the groups prepare a poster presentation of their findings
• Create stations that have the different setups in the handout and let the groups rotate through them

Classroom Considerations

• Either purchase gilley coil sets or make coils so the groups can perform the activity
• The 12th in a 14-part series

Pros

• The resource provides a listing of materials needed
• The handout includes diagrams for how to build the circuits

Cons

• None
