You have a small bar magnet and a coil with 100 turns, each with area 2.6×10−4m22.6×10−4m2. The magnitude of the B⃗ B→ field at the front of the bar magnet's north pole is 4.0×10−2 T4.0×10−2 T and reaches 0 TT when it is about 4.0 cmcm away from the pole.

With what speed should you move the magnet to make the bulb light?
