Question about Electromagnetic Induction: Induced EMF

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?

Solution Summary

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