1. The problem statement, all variables and given/known data A 5-turn coil 1.0 cm in diameter is rotated at 10 rev/s about an axis perpendicular to a uniform magnetic field. A voltmeter connected to the coil through rotating contacts reads a peak value of 360 uV. What is the magnetic field strength? 3. The attempt at a solution B=u_{0}nI u_{0}= 8.85 x 10^{-12} C^{2}/N m^{2} n = 5 I'm not exactly sure how to find the current. I know that the induced EMF = Blv, but I don't know what to do about length. v=omega*r = 0.05 m/s So, once I find either the length or the current, I should be able to find B.
