Today, we started investigating electromagnetic induction in AP Physics 2. I demonstrated how inserting a magnetic into a solenoid resulted in a current in the solenoid that could be measured with a galvanometer. We then discussed as a class what variables may affect this induced current. The students thought of enough variables such that each of the six groups qualitatively investigated a different variable. After investigation, each group demonstrated their investigation and shared their results with the rest of the class.
