Question

Choose the option that has both a four-loop coil and a two-loop coil. Experiment moving the magnet around and answer the following questions: 1. In terms of the current, what is the difference between positive voltage and negative voltage? 2. Using just the two-loop coil, how do you increase the strength of the voltage signal? 3. What is the difference in the voltage signal between moving the magnet with the North pole facing the loop and moving the magnet with the South pole facing the loop? 4. What is the difference between experimenting with the two-loop coil and the four-loop coil?
