Electromagnetic Induction
Charges moving in a magnetic field create an electric field, just as charges moving in an electric field create a magnetic field. This is called electromagnetic induction. Induction provides the basis of everyday technology like transformers on power lines and electric generators.
On average, SAT II Physics asks only one question about electromagnetic induction. However, less than half of the test takers usually get this question right, so if you get the hang of this material, you’ll be separating yourself from the crowd. On the whole, this question will be qualitative, with only a minimum of calculation involved.
