A generator can be made using the component of Earth’s magnetic field that is parallel to Earth’s surface. A 162-turn square wire coil with an area of 4.41 10-2 m2 is mounted on a shaft so that the cross-sectional area of the coil is perpendicular to the ground. The shaft then rotates with a frequency of 18.0 Hz. The horizontal component of Earth’s magnetic field at the location of the loop is 5.00 10-5 T. Calculate the maximum emf induced in the coil by Earth’s magnetic field.
