One generator uses a magnetic field of 0.10 T and has a coil area per turn of 0.045 m2. A second generator has a coil area per turn of 0.020 m2. The generator coils have the same number of turns and rotate at the same angular speed. What magnetic field should be used in the second generator, so that its peak emf is the same as that of the first generator?
