A generator can be made using the component of Earth's magnetic field that is parallel to Earth's surface. A120-turn square wire coil with an area of 3.94×10^-2 m2 is mounted on a shaft therefore that the cross-sectional area of the coil is perpendicular to the surface. The shaft then rotates with a frequency of 20.3 Hz. The horizontal component of the Earth's magnetic field at the location of the loop is 5.00 ×10^-5 T.
Estimate the maximum emf induced in the coil by Earth's magnetic field.
Answer in units of V.
