1. With the equipment in front of you, slowly insert the north pole of the bar magnet into the coil. Is the induced current positive, zero, or negative? (circle one) (2 points) Is the induced current small or large? (circle one) (2 points) 2. Based on your answers in question 1, predict the characteristics of the induced current in each of the following scenarios: (4 points) Scenario Sign of current Magnitude of current Insert north pole into coil, slowly Positive, Zero, Negative Large, Small Insert north pole into coil, quickly Positive, Zero, Negative Large, Small Put north pole inside the coil, and hold it there Positive, Zero, Negative Large, Small Pull north pole of coil, slowly Positive, Zero, Negative Large, Small Pull north pole of coil, quickly Positive, Zero, Negative Large, Small Put whole magnet inside the coil, and hold it there Positive, Zero, Negative Large, Small 3. Now, turn the magnet around and predict the characteristics of the induced current (4 points) Scenario Sign of current Magnitude of current Insert south pole into coil, slowly Positive, Zero, Negative Large, Small Insert south pole into coil, quickly Positive, Zero, Negative Large, Small Put south pole inside the coil, and hold it there Positive, Zero, Negative Large, Small Pull south pole of coil, slowly Positive, Zero, Negative Large, Small Pull south pole of coil, quickly Positive, Zero, Negative Large, Small Put whole magnet inside the coil, and hold it there Positive, Zero, Negative Large, Small Discussion Questions 1. How does the speed at which you move the magnet affect your results? (10 points) 2. In any situation where the magnet is not moving (inside the coil or outside the coil), you get zero current. Why does this happen? (10 points) 3. What are two changes you can make to your experimental setup to get a larger current produced? (Assume the type of wire in the coil is not changing) (10 points) 4. In this entire experiment, you were moving the bar magnet into/out of the coil. If you keep the magnet stationary but move the coil instead, will your results change? Why or why not. (10 points) 1.
