The pickup coil in an electric guitar contains 10,000 turns and has a diameter of 2.0 mm. When the pickup coil is very close to a guitar string, there is a field of magnitude B = 0.10 T in the coil. If this steel string is vibrating at a frequency of 200 Hz, what is the approximate maximum emf induced in the coil? For simplicity, assume the induced flux varies back and forth between zero and the value found when B in the coil is at its maximum value (found when the string is very close to touching the coil).
