    Question about Electromagnetic Induction: Induced EMF

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    A) A 50-turn loop of wire has a cross-sectional area of 0.010 m^2. It is rotated about an axis perpendicular to the earth's field of 5.0 × 10^-5 T. What is the peak value of the emf generated if the loop rotates at 3600 rotations per minute?

    b) What would be the peak emf of the generating coil in the example above if it were turned in a magnetic field of 0.100 T?

    b) What would be the peak emf of the generating coil in the example above if it were turned in a magnetic field of 0.100 T?

    I believe the answer for b) 190 V. I need to see each step and formula to solve ...

    Solution Summary

    The coil is rotating in the magnetic field and the peak value of induced EMF is calculated. Faraday's law is discussed.
