You want to use the idea of electromagnetic induction to make the bulb in your small flashlight glow; it glows when the potential difference across it is 1.5 V. You have a small bar magnet and a coil with 100 turns, each with area 2.9 Γ 10β4m2. The magnitude of the Bβ field at the front of the bar magnet's north pole is 3.6Γ10β2 T and reaches 0 T when it is about 4.0 cm away from the pole.
a) With what speed should you move the magnet to make the bulb light?
b) Can you make the bulb light? (yes/no/need more data)
