Introduction: Mastering Physics Currents and Magnetic field

More Details: A 8-turn coil 1.9cm in diameter is rotated at 15rev/s about an axis perpendicular to a uniform magnetic field. A voltmeter connected to the coil through
rotating contacts reads a peak value of 320 $$\mu$$ V. What is the magnetic field strength?
